I'm getting the Firebird 2.5 superclassic server on Linux deadlocking
regularly at the moment. Twice in one day last week, and again today
after uptime of less than 6 hours.

I just upgraded to 2.5.8 today, from 2.5.6. Our workload isn't huge, but
we do have a lot of small databases and maybe up to 100 client
connections at once.

I attached gdb and dumped the state of all threads, which shows every
one of them is waiting on a mutex or futex, ie it's dead locked. I've
attached the trace.

How can I debug this?

Would I be better off with superserver?

I can't connect with isql when it's in this state (it hangs).
