I hit another segfault today, my server was setup to shut down around 4am, and it did shut down without problem, but the problem is that it got rebooted right after the shut down and after that, I see segfaults in the syslog (I have rsyslog setup).
I have reset my motherboard's BIOS, the reboot after shut down was solved, and no segfaults in the syslog so far.
I'll continue to monitor for another few days, and if there's no problem, I'll mark this as solved.
