Segmentation fault (core dumped)

[okarpov]

After some time of running dotnet application we get the error message in subject.

How to find out the root of the issue which causes this error
and where are the core dumped files saved?

Ubuntu Server 20.04

here is what i have found so far:

root@server: dmesg | grep segfault
[1157149.729375] .NET ThreadPool[2478560]: segfault at 6f1 ip 00007ffff7b639e0 sp 00007ffcfdff9ca0 error 4 in libc-2.31.so[7ffff7a82000+178000]

and this:

root@server:/var/crash# ls
_usr_share_dotnet_dotnet.0.crash

but how now understand what happened and where the crash was?
