Issue with Server Deadlocks - Logs and Thread Dumps

Hello,

I've been encountering deadlocks in the codebase, and I've gathered some logs and thread dumps for reference.

The majority of the attached server logs pertain to the auto-ban functionality, which has been triggering alerts due to abnormal behavior. It's worth noting that this behavior is itself unusual for the auto-ban module. Additionally, the server log file reveals an unusual pattern labeled as "spamming TYPE 4," a behavior that has been observed in previous deadlock instances as well.

The thread dumps provided in this issue are part of a complete thread dump, which is attached at the end for your review.

Thank you for your attention to this matter.
