Hi,
I've been looking at reported problems with our Vdeio Conferencing kit attched to a stack of 3750's (which I think is down to QoS) but this got me looking at the logs. We get a lot of high CPU utilization warnings mainly for SNMP (315), Hulc running con (95), Virtual exec (289). I understand the last two are normal, and the SNMP one is probably Cisco Works polling as it happens every 4 hours.
However I've got an odd one:
Apr 25 07:34:58: %SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 93%/0%, Top 3 processes(Pid/Util): 296/85%, 144/0%, 154/0%
What is Pid 296? It's not listed on the switch:
293 39056 18456 2116 0.00% 0.00% 0.00% 0 SpanTree Helper
294 8 73 109 0.00% 0.00% 0.00% 0 EEM Server
295 0 2 0 0.00% 0.00% 0.00% 0 EEM Policy Direc
297 0 2 0 0.00% 0.00% 0.00% 0 EEM ED CLI
298 0 3 0 0.00% 0.00% 0.00% 0 EEM ED Counter
SW_001#sh stacks 296
No such process #296
It's only appeared once in the log, so I'm not worried, but it's made me curious. Any ideas?
If anyone could shed any light on this one as well it would be appreciated (320 crypto sw pk pro):
Apr 24 19:46:04: %SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 80%/0%, Top 3 processes(Pid/Util): 320/74%, 69/0%, 71/0%
Thanks

Hi Will,
Can you please get me the following outputs:
show proc cpu sorted | ex 0.0
show proc cpu history
show controllers cpu-interface
show platform port-asic stats drop
accordingly.
Also Please look at troubleshooting CPU on 3750 on below link:

Hi Will,
I dont see any issue with the CPU utilization as of now:
sw_001#show proc cpu sorted | ex 0.0
CPU utilization for five seconds: 6%/0%; one minute: 7%; five minutes: 7%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
154 29021790 17711677 1638 0.31% 0.25% 0.24% 0 HRPC qos request
Hence we cannot do any troubleshooting now as the cpu utilization has back to normal.
HTH

Thanks for looking. I don't think there is much to worry about, I was just a bit curious about that one.
