Describe the bug

Fluent-bit pod deadlocks, causing CPU to rise, no further log processing happens. I created a core dump and examined it:

To Reproduce

I am not able to reproduce at that moment. This doesn't happen frequently.

Expected behavior

No deadlocks. The only solution currently is to monitor pods that reach their CPU limit and kill them.
