Description

My program got stuck on dotnet 9 rc2 randomly, about once a day. Even Ctrl-C can not terminate the program on this situation. but It is running ok for months on dotnet 8.

Here is dotnet version dotnet --version 9.0.100-rc.2.24474.11

linux version(uname -a) Linux ip-172-31-19-202 6.8.0-1017-aws #18~22.04.1-Ubuntu SMP Thu Oct 3 20:15:06 UTC 2024 aarch64 aarch64 aarch64 GNU/Linux It is aws c7g.8xlarge.

Here is coredump backtrace. (gdb) bt
