High CPU Utilization

‎02-03-2014 01:38 PM

My SRX240B (11.4R9.4) is logging constant CPU threshold exceeded messages:

Feb  3 07:10:13  sdl-f-jun001 PERF_MON: RTPERF_CPU_THRESHOLD_EXCEEDED: FPC 0 PIC 0 CPU utilization exceeds threshold, current value=95
Feb  3 07:10:22  sdl-f-jun001 PERF_MON: RTPERF_CPU_THRESHOLD_EXCEEDED: FPC 0 PIC 0 CPU utilization exceeds threshold, current value=100
Feb  3 07:10:25  sdl-f-jun001 PERF_MON: RTPERF_CPU_THRESHOLD_EXCEEDED: FPC 0 PIC 0 CPU utilization exceeds threshold, current value=88
Feb  3 07:10:31  sdl-f-jun001 PERF_MON: RTPERF_CPU_THRESHOLD_EXCEEDED: FPC 0 PIC 0 CPU utilization exceeds threshold, current value=89
Feb  3 07:10:39  sdl-f-jun001 PERF_MON: RTPERF_CPU_THRESHOLD_EXCEEDED: FPC 0 PIC 0 CPU utilization exceeds threshold, current value=97
Feb  3 07:10:43  sdl-f-jun001 PERF_MON: RTPERF_CPU_THRESHOLD_EXCEEDED: FPC 0 PIC 0 CPU utilization exceeds threshold, current value=99
Feb  3 07:10:46  sdl-f-jun001 PERF_MON: RTPERF_CPU_THRESHOLD_EXCEEDED: FPC 0 PIC 0 CPU utilization exceeds threshold, current value=93
Feb  3 07:10:56  sdl-f-jun001 PERF_MON: RTPERF_CPU_THRESHOLD_EXCEEDED: FPC 0 PIC 0 CPU utilization exceeds threshold, current value=100

 

Nothing stands out in task accounting. There are no dropped packets. I am running just the default IDS with no AV or anit-spam. The routing engine is at 95% idle.  One thing I do notice - increase in download rate severely affects upload rate. See attached. 

 

Any ideas?

 

Thanks

Darrell

You can try to figure out what is causing th eissue, but it seems like one for JTAC. I would also look at upgrading to the least the recommended version first.

Out of curiosity, do you have any traffic policers setup?
