We need a small test case that can reproduce your problem.  I believe https://github.com/python/cpython/commit/3b699932e5ac3e76031bbb6d700fbea07492641d to be correct.

acquiring locks before fork in the thread doing the forking and releasing them afterwards is always the safe thing to do.

Example possibility: Does your code use any C code that forks on its own without properly calling the C Python PyOS_BeforeFork(), PyOS_AfterFork_Parent(), and PyOS_AfterFork_Child() APIs?
