Cisco WAN :: High CPU Utilization In GGSN (7604 Ios 12.4)
Jul 26, 2011
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.
------------------ show process cpu ------------------
CPU utilization for five seconds: 50%/15%; one minute: 49%; five minutes: 51%

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 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 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.

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.

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.

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 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
IOS version 8.0(4)
sh cpu usage
CPU utilization for 5 seconds = 51%; 1 minute: 61%; 5 minutes: 58%

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.

My client using 3845 as a core router . 200 number of branch are connected through 6 ISP.Some of days average process shows 90 % . Max time 50 %.In the morning when Branch location are off then time also high utilization.High utilization is not continue after intervals of time or periodic time its goes to high.
have any solution for that ?. before once 3845 is crash for that. another is ready for replacee.We test another device like core switches for observation CPU rate.

I have a router 2811 and shows high CPU utilization 90%, it is observed that this happens when the traffic increases, the router also has firewall enabled services, QoS, DHCP, ACLs, NAT. As my router could not determine what is appropriate for my use, and how it could choose a router that meets my needs.

I have problems with the Router 2801.When i give the command show processes cpu, the command show me that the router is working in 98%.
I have vlans like voice vlan and others, I have one 20 Mb Wan Link and I redirect all traffic from my lan to this link and when i browse in internet or i do downloads the router goes to 98%, when i don't make it the router processes goes down.
I thought be problem with hardware, but i exchange to another router and the same problem happened.Before this situation, I had one link with 12 Mb and nothing happened, when i exchange this to the 20 mb link the problems starting.

We are facing a weird problem of high CPU utilization on 3560 switch. Even without connecting a single PC to switch, CPU utilization is showing 22 %. Any particular reason for this? Can configuration affect the CPU utilization even though there is no PC connected?

there is no logging in the access-list (there is only one inbound access list).Using QoS or not, doesn't seem to make a differenceAll route-caching features are ON. (CEF, Flow, Policy, Fast)Yet the minimum CPU utilisation I have seen is 25%/25%... On average it's 40% during the day, but once traffic picks up to around 6000 packets per second, the router is gone...I have a 50/50 Mbps connection, but I can use only 6 for VoIP ?
