Describe the bug
As its name indicates, I happen to have a problem of deadlocks with some OpenSSL's libcrypto's mutex acquisition calls.

To Reproduce
I am not able to reproduce this bug, it heavily depends on the load for the servers and the concurrent calls from multiple processes to functions using libcrypto.

Expected behavior
Not having a deadlock 😅

Relevant System Logs
You will see below a full stack trace (that I got with opensips-cli) that showcases the deadlock. You can also see that there are several calls to "get_static_lock" that seem to be part of the problem but it is not, I was trying to mitigate (or completely suppress) the risk of a deadlock by locking the different parts of my opensips' script that were calling methods using libcrypto (but it would be better to try to fix the root cause of the problem).

I had to anonymize the sensitive data inside the stacktrace but none of these data is relevant for my issue.

OS/environment information

• Operating System: openSUSE Leap 15.4
• OpenSIPS installation: recompiled OpenSIPS 3.3.7 (with some custom patches but they don't affect the bug) linked with OpenSSL 3.0.0

Feel free to ask for any additional information.
