When I am using "perf record -F 99 -g -p -- sleep 300" during average load, I am getting the perf.data file without any problem. But when the load is high, it is crashing. The only way to get an ok result is to reduce the frequency to around 30, which is terrible.

Ideally, the rate should be high to get better results(about 997 samples/sec). Is there any solution to this.

I think that the issue might be related to the Linux kernel space. If so, what would I have to do to solve this issue?

  • How does the crash look like from the console? Could you post the stacktrace of the crash?

  • Hi,I am not getting any stack-trace when it crashes. Is there any way to generate the stack-trace as it is not coming by default. Also. should i add anything in the "perf record" statement to get the stack-trace.

  • Below is the stack trace that i got : [root@finesse25 ~]# perf record -F 9997 -g -p 23675 -v Warning: The cycles event is not supported, trying to fall back to cpu-clock-ticks Using CPUID GenuineIntel-6-3E-4 mmap size 528384B couldn't open /proc/14480/status Note that I have used -v (perf record -F 9997 -g -p 23675 -v) as an extra argument to the one mentioned in the original question. (perf record -F 99 -g -p -- sleep 300)
