perf record -f is crashing during heavy load #89

Hi, when i am using "perf record -F 99 -g -p -- sleep 300" during heavy load, it is crashing. Only when i reduce the frequency to around 30, i am getting results.Ideally, the frequency should be high to get better results(around 997 samples/sec). Is there any solution for this.
