We suddenly noticed high CPU utilization on one of our 7600 routers. I output of show process CPU showed high utlization for the FM core process. I looked it up but did not find information on what this process does. [code]
how to resolve high cpu to interrupt.I am getting lots of input que drops in all vlan interfaces.I have enabled multicast in all vlan interfaces. System image file is "sup-bootdisk:s72033-advipservicesk9_wan-mz.122-33.SXI4a.bin"
I have an issue with 7600 router where CPU goes up to 60-70% and memory is also high. Both due to BGP Router process. URL We are seeing this issue since ISP has upgraded their router 20 days ago. Router also seen following error.I have not reset the BGP session with ISP yet. Is there any way I can supress BGP updates coming from ISP and see if CPU and memory USAGE reduces. IOS version 12.2(33)SRD and RSP720 with PFC 3cXL
I have an issue with 7600 router where CPU goes up to 60-70% and memory is also high. Both due to BGP Router process. [URL] According to our baseline it should not be more than 40% at any given time. We see high CPU uptp 70% consistently.

Router has 1 eBGP session with ISP from where it downloads whole IPv4 internet routing table and two IBGP session with other two rotuer. When I look at BGP summary table I see many updates received from ISP and sent out to IBGP neighbors. Also did debug BGP updates to confirm it.

I am a little stuck trying to troubleshoot unusually high cpu on 7600 Platform.This has been going on for many hours and not been causing a problem, but this doesn't seem replicated in our network and I am concerned about the cause.I have attached some output below, and disabled netflow on interfaces to free some switching CPU. How to track the cause of this? We only have routing protocols and 5 static routes to Null 0, so I cant see how this can be a route loop, but willing to stand corrected. Routes are learned from BGP with OSPF/MPLS internally on the network. This switch also connects to access switches on RIP and EIGRP.
No change has been made to this device when this problem started to occur so I am suspecting something about the traffic has changed or there is a rougue user? [code]
Our Router 7606 is in a problem with high CPU Utilization. We are using one EBGP and one IBGP session. We are also running OSPF with area 0 between two IBGP router to exchange few local networks. When bandwidth cross 100 MB than only CPU use become 100%. when bandwidth consumption is 80MB CPU use become 80% end so on.
Out put is when bandwidth consumption is 34MB

I have a hight CPU utilisation problem in my CISCO7609-S routers. the cpu utilisation can rise 99% et this is usually. In the moment of hight CPU the the process CPU give the following:
I have a 2811 that is really hitting the CPU hard. Nothing shows on CPU processes. It has an IPsec VPN tunnel back to HQ which also has a 2811 that terminates the VPN. The HQ has 2-3 IPsec tunnels to other remote sites. The CPU at the HQ avg 50% utilization during business hrs, peaks at about 80%. The remote one is very high 95% peaks, avg 80%-95% during business hours with bandwidth utilization of only 10-20Mbps. I read somewhere that its possible that fragmentation could be causing this. My question is, if I set the MTU to 1450 on the remote, I am guessing I will need to do all the other routers as well, the HQ and other remote sites? Siince they use the same outside interface to my HQ, is that correct?
I am observing very high CPU utilization on my Cisco 7206VXR (NPE-G1) Router. We have done all the necessary troubleshooting but not able to identify root cause. [code]
I am running Cisco Prime 4.2(UNIX version) on a VM. CPU utilization will run between 90 and 100% constantly. Reloading the server will stabilize the CPU for a short period of time, however the CPU usage will always return to 90-100% utilization. Currently I have about 130 devices added to the system.
we have 2 Cisco C4507 Switches working As Core Layer, but the CPU Utilization is about 54% most of the time and sometimes it goes up to 70% or 80% also.
which services are causing this utilization. [code]
I am working as net admin which is i need to monitoring and manage my workplace network( education center )I got a few question about network traffic flow. Here is the issued.I got high bandwidth utilization so high after office hours which is only on night. as we know, after office hours there is no person at the office but the traffic flow on bandwidth utilization is high.what are the possibilities of this issued?
Is there any commands to know the Current Heat Dissipation of high end routers and switches 7600,6500? Even though we can calculate thro. corresponding calculators, i eager to know is there any commands to do that?
I have Cisco 7613 on my edge(MPLS Backbone). CPU utilization is shooting to 100% at frequent intervals. When I tell vendors managing device they tell that it is happening due to one of my server(connected on Fast ethernet port of 100Mbps) generating heavy traffic. My questions are:
1. Can a router of 720Gbps capability be choked due to traffic generated by 100Mbps link?
2. Interrupt CPU process utilization is well below 10% at the said time. BGP router process consumes most of the CPU. Does this means that server in question is generating too many routing updates?
3. Is there any way that I can limit routing updates on a particular link?
4. how to check which link is causing more CPU utilization.
My router is running with BGP (One eBGP and One IBGP session). I have filterdown the BGP roting table by using prefix-List and default route to upstream router.But still found the CPU process is high (80%/80% with 60MB traffic).

I have Active Standby ASA5550 setup with VPN premium license. A few days back we had a requirement of SSL VPN connection for and we got a temporary from Cisco for same, this license expired and the ASA reverted to it's original license. 3 4 days after this we saw a sudden increase in CPU utilization (upto 90% + -5%) on the ASA during production hours but were not able to figure out the reason, in order to restore the services we failovered the firewall to secondary and everything worked fine. We were suspecting one of the following but there were no logs for any of this
1. The ASA hardware was haivng problem
2. Some client was doing a DoS attack to bring down the ASA (no logs for this as well).
We took a downtime to look further by failovering the ASA back to primary and it worked fine without any issues ruling out the 1st option. We also came across a licesing doc [URL]
Downgrading any license (for example, going from 10 contexts to 2 contexts).
# Note If a temporary license expires, and the permanent license is a downgrade, then you do not need to immediately reload the security appliance; the next time you reload, the permanent license is restored.
As per this doc, sooner or later a restart was required on the ASA. We restarted secondary ASA and everthing was fine but when we restarted the primary ASA by swtiching over to secondary some of the server (not all) in the DMZ stopped working (even ICMP unreachable) and only came back to normal when the primary ASA was restored and working fine (with failover).
The reboot was done by shuting down the physical link between the Core switch and ASA inside individually.
I am not sure what could be the issue that the servers in the DMZ wen unreachable.
We have a CISCO 7604 Router (GGSN) in our customer site. Since two weeks are observing high CPU utilization (even touching 100 percent). We performed a SNMP configuration on this routers 2 weeks back as well. But SNMP process is not consuming much CPU resources. The following is the output of the "show proc cpu" and "show proc cpu history.

I have a 7206VXR router doing policy routing with CEF enabled on all interfaces, no Cache Misses, Align Errors or failed buffers. CPU peaks up to 80% every two or three minutes. I suspect it is traffic related as I have a standby box and when it becomes the active on in the HSRP pair to high CPU load and LAN interface input errors follows it. see various show command output below. The router has a NPE-G1 and I'm using a gigabit port off of this on the LAn side and a E3 Frame Relay interface on the WAN side.

I have a remote site customer with a Cisco ASA 5540 running SSLVPN (Anyconnect)(8.03). It currently only serves about 450 SSLVPN clients. Since last friday, they've seen the CPU utilization go up to high 90% while only serving 400+ remote users. I saw some high cpu utilization bugs, but none looked to be relevant. How I can find the root cause of the CPU high utilization?
I am facing lots of issue with cisco 4507 switch recently.. Every alternate day, its CPU is getting utilized by 99% and network stopped working..finally it has to be restared.
Below is the CPU utilization of the process:-

we have ASA 5520 with IOS 8.0 , when i am trying to add more static routes on the inside interface the CPU utilization is going up. one faced the same issue. I am configuring through the cisco ASDM 6.1(3)f.
I am facing high CPU util on my pix 515 E which is in failover mode.During peak hours the util is see rising to 60% where as in off peak hours it is normally12%.
During normal operation the average utilisation was observed to be 30% but suddenly from 2/3 days it is constantly 60% doule the value as earlier. Have gone through the logs and traffic but not able to tarce anything particular
below is the o/p of some command taken for analysis

I have a Router 2821 with c2800nm-advipservicesk9-mz.124-24.T1.bin and with a Cisco Integrated Service Engine(s) Cisco Unity Express 7.1.1 in slot 1 , this router shows a high cpu utilization.I think is a bug with the IOS , because there is no voicemail configured on the CUE, there is no traffic to the CUE , just traffic from:
- voice calls - ospf
The ospf is not the cause of the high cpu , because the high cpu utilization appears before I put the ospf proccess on the router.
