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.

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]
When a physical switchport/routed port has high usage, you can move the link to a higher capacity port, upgrade the port, bond links, etc. What exactly do you do when an SVI has high usage? I guess you could remove some servers from the VLAN, but that doesn't seem like a reasonable solution. What dictates the capacity of an SVI? The backplane of the switch?
I have a 1841 router plugged into a 100M Comcast ethernet connection. My router cpu is really high and users download speed isn't as high as before. Can a 1841 handle 100M circuit with 100 users on it? What would cause the router's cpu to be high? I don't think there are any viruses or malware on the lan.

I have a lot of cisco 7206 vxr deviceses. I have a high cpu problem.I have a 7206 vxr g2. I used to use ebgp for three upstream carrier. I used to bgp full route table method. I have about 800 Mbps active traffics and behing the router about 1600 active customers.
How can I trouble shoot this high cpu problem?

I have a Cisco 1921 router and it uses 99% of CPU and i cant seem to spot wich process that is taking up the cpu. I have an interface with several sub-interfaces and i am moving data between two of those subnets, i tried the "ip route-cache same-interface"-command on giga bit ethernet 0/1 with all the sub-interfaces like gigabitethernet 0/1.18 and so on. That did not work.
Received this notice from ISP. Does this make sense:We have noticed we are getting a huge number of queries from X.X.X.X and it is showing to be about 98% of the DNS traffic hitting our name servers. It appears that the data consists of reverse lookups to 10.1.0.0 network. It needs to be remediated as soon as possible because it could cause a service interruption.It almost seems as if my router is acting as a DNS server. The isp data consists of reverse lookups to 10.1.0.0 network which would be the internal.
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]
I've got a problem with a core 6509E and the multicast.A client has a system with cams for the physical security and they are connected to a vlan with this config:
interface VlanXip address 172.20.167.1 255.255.255.128ip helper-address 172.20.32.7ip pim version 1ip pim sparse-modeendThe thing is that we know that one server that shows the cams at the security office is flooding the network and the CPU CORE is over 95% always:

i keep getting messages from AVG saying they have detected a very high internet usage, first it was with google and then with firefox..they recommended to shut down and restart..anyone could explain what's going on? I'm not downloadin anything..just checking my mail!
Recently got a mobile broadband dongle for my laptop, shows 7.2 Mbps speed in the status window and under activity the received bytes is shooting up, as I write this is has went from 25,000,000 to 35,000,000, that's about 10 mg for a few seconds, it does this even when I have no page open, I can't see anything in task manager, I don't know why it's downloading so fast when there's nothing there, also because of this it is slowing my browsing down,
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?
My 4500 core always in 60 % cpu utility , and when i run #sh proc cpu sorted i find that 55 29725041543795572214 0 39.43% 41.40% 41.39% 0 Cat4k Mgmt LoPri
Which mean that this process is the top one , and when i run #sh platform health i found that Stub-JobEventSchedul 10.00 15.98 10 64 100 500 20 17 12 29269:55 K2 CpuMan Review 30.00 35.60 30 48 100 500 49 46 32 52390:52
Those two process are the top and they already exceed their maximum rang and when i run #sh platform cpu packet statistics i can find that Packets Received by Packet Queue
My CAT 4510 switch is showing 99.9% CPU usage almost through out the day. After some analysis i saw that the “Cat4k Mgmt LoPri” process is having 86% CPU utilization. This process is a package that is including multiple process.
Within this package, two processes have been identified which are causing this shock which are “K5L3Unicast Adj Tabl” and “K5 L2 Hardware Addre” .
This indicates that some heavy activity is going on CEF adjacency table and RP MAC Address Table. My current IOS version is 12.2(53)SG
I have configured an ASA 5510 and 2960S 48 port switch in a lab environment. I have two laptops connected to seperate subinterfaces with server 2003 as dhcp server for one network. Everything has been working fine as we have been testing the ASA while also testing the csc smm module. When we came in today we noticed the csc module cpu is running at 100% constantly and http traffic is extremely slow. I have not yet received my smartnet contracts from the vendor or I would open a TAC case and I have read on the net that this is a common problem.
I recently reboot my asa 5520, I was trying to remove webvpn listening from my outside nic, even though it wasn't configured. [code]I was planning to do another reload without the fast reload option.
I have ASA that just started to reboot through out the day yesterday. It seems to happen every few hours but not in a pattern.Right before it reboots there is a flood of sys log id 305006 messages "portmap translation creation failed for tcp src inside:xxx dst outside:xxx the xlats go from around 2-3k to about 30+k then crash.Memory ussage is already pretty high normally on this device (about %75 used) CPU is around %15-20 I notice that the portmap translation errors are always from 3 inside host.
I'm having issue with one stubborn process that is consuming nearly all the CPU on all of my switches. I tried googling it, but had no luck. The process is "hulc nrgyz PD di"
We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high. This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure. Below I provided some outputs about how to diagnose it.
I have a 2 Cisco 3750X stacked working as CORE switches but not in production yet showing a high CPU utilization and I would like to see with you whether you think this is normal or a IOS upgrade/downgrade should be performed.
I have very low traffic coming through as this is not yet in production:
We have two c6509 budled in VSS. I have noticed randomly high usage of CPU, sometimes up to 99% in peaks. I have found that it can be generated by SNMP engine. So I unconfigure all SNMP things. But situation is the same. I would like to know if this state is OK or not. CPU shows are enclosed in file.
I have a couple of Switches Blade 3120, working as active-standby model (HSRP) on a new site deployment. There are other 20 sites more or less, working on the same model, without issues. But in this one, we are seeing a high cpu usage. The traffic going through the platform is 600Mbps (on peaks), and in this case we have 40% of CPU usage. Traffic should be close to 3 Gbps. When we tried to send the whole traffic through the platform, active switch began to drop packets on the majority of interfaces.
When we analyze the CPU usage, there is a special process called "HL3U bkgrd proce" always have the most CPU use, but we do not know what concerns. We do not know if it is caused because there are PBRs configured. It should not matter. How I mentioned, there are other sites working fine and have had always the same PBR number.
What is causing the high usage?. Is there a special debug we could to perform to diagnose the issue?. Also, we have seen a high interrupt CPU usage (9% in this case).

hardware version is WR841N v8.wireless works just fine. i use it for my smartphone and an old laptop. i use ethernet cable to connect to main computer where all is ok until i start using my bit torrent client. as soon as i build up traffic above 1MB the ethernet portion of the router freezes and needs a reboot. when frozen, wireless is still working and i still have access on the lan to the router via my browser. i got this router so i could have wifi for my phone. my old router (asus rx3041) worked just fine and i accessed my isp at the maximum speeds it would allow on a 60 gigabit connection.
