使用perf想看一下火焰图，有两个问题：
1.perf record ctrl+c不了，是做了什么操作？我本地其他程序可以正常work。
2.perf report、script等会报错perf.data为0，实际上perf.data里面有一些数据。

Reading /proc/10732/task/10732/maps time out. You may want to increase the time limit by --proc-map-timeout
[paxtest@ip-192-168-218-224 StarRocks-3.2.3]$ perf report
WARNING: The perf.data file’s data size field is 0 which is unexpected.
Was the ‘perf record’ command properly terminated?
