Dead loop occured when doing perf

[choxsword]

The pictures above are generated by pstack and gdb. The async_profiler is maximizing CPU usage and does not exit. It seems that there is a spin lock which is not got released, leading to such dead loop issue.

What profiler version are you running?
Can you show stack traces of other threads?

What profiler version are you running? Can you show stack traces of other threads?

version is Async-profiler 2.7 built on Nov 25 2022. The primary scene has already been lost. So I'm sorry that I cannot provide more informations except the exsisting one.

Other threads are our business threads, they all runs normally.

There were many fixes since version 2.7. Please try an up-to-date version of the profiler.
2.7 is no longer supported.

I'm closing the bug assuming it has been already fixed. Feel free to reopen if you encounter this again with a recent version.
