Package: firebird2.5-classic
Severity: important
Tags: squeeze

Firebird, namely fb_inet_server, segfaults several times per day. I tried
-super, -superclassic too, but the classic one is crashing less frequently
than others.

I'm running it on fully updated Squeeze on a Dell AMD64 server. Squeeze is
32-bit. Everything else except Firebird do work like a charm.

More connections leads to more crashes. In other words, when I do use just
one client, it crashes several times per day. But when I do use two or more
clients, it's dead in 30 minutes and I can't no longer use Firebird - can't

I have these errors in /var/log/firebird2.5.log

 - INET/inet_error: read errno = 104

Sometimes when I'm killing fb_inet_server processes, I have these messages
in firebird log ...

 - Firebird shutdown is still in progress after the specified timeout
 - Operating system call pthread_mutex_destroy failed. Error code 16

And system log does contain these messages ...

.... no idea what can be wrong. Willing to test anything. It's on production
server and we have live data in this database.
