Thread safety issue

[layters]

Details

So the code for the backend (neroshop daemon) is not thread safe and sometimes random segment faults occur and I'd often get deadlocks when using mutexes. I have no knowledge in threads or thread-safety practices so I need someone far more knowledgeable than me who can help make this as thread-safe as possible.

There are countless threads being used and many threads are within other threads which probably makes the issue much worse I think.
