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
- Gentoo Linux 2006.1 for AMD64
- CFLAGS="-O2 -march=nocona -pipe"
- 350GB RAID-5, filesystem ext3

I am pretty sure that the hardware is ok, it's server-class hardware and

Is there anything to worry about or is this normal?
