icexelloss opened a new issue, #41862: URL: https://github.com/apache/arrow/issues/41862
### Describe the bug, including details regarding any error messages, version, and platform. I am seeing a deadlock when destructing an ObjectOutputStream. I have attached the stack trace. I did some debugging and found that the issue seems to be that the mutex in question is already held by this thread (I checked the __owner field in the pthread_mutex_t which points to the hanging thread) Unfortunately the stack trace doesn’t show exactly which mutex it is trying to lock. I wonder if someone more familiar with the IO code has some ideas what might be the issue and where to dig deeper?
