New description:
The backend deadlock with multiple (33) Delete Threads
waiting on a mutex.
Full backtrace is attached (it's at the end of the file,
there's a short backtrace first, then a thread summary)
Comment:
Not a bug.
These threads are waiting for their turn. Only one delete proceeds at a
time so we can rate limit deletes. If a large file delete happens due to
an auto-expire or user request and then you do a lot of channel flipping,
many small deletes will bunch up waiting for the delete lock. Within a few
minutes they will all get their turn and execute quickly.
