Hi List,
I have a server where i see the following messages sporadically (about
5-10 times per day):

Other than that, the server seems to work without problems. I haven't
been able to catch any problems related to these segfaults. I also
haven't seen any database corruption.

Here are the system details:
- Dual Xeon Model 4 3.2GHz
- Hyperthreading enabled
- 4GB RAM
- Gentoo Linux 2006.1 for AMD64
- CFLAGS="-O2 -march=nocona -pipe"
- 350GB RAID-5, filesystem ext3

I'm running Firebird 2.0.1 Classic. I've tried both with my
self-compiled version (Firebird-2.0.1.12855-0) and the precompiled
version (FirebirdCS-2.0.1.12855-0.amd64) which both produced the same
errors.

I am pretty sure that the hardware is ok, it's server-class hardware and
I've never had any other process segfaulting.

Is there anything to worry about or is this normal?

Michael
