Hello all FreeBSD fans,
I have a nasty problem which makes my server crashes at random period and until today I even didn't have some kind of error message which could points me where the problem could be.
I use 6.2-RELEASE mainly as mail server, running postfix with dovecot. At the today's crash I've manage to record an error message on the screen:
I'm not sure what this message means, but to me it seems like some hardware problem. Another suggestion is that the crash is caused by some faulty process, but how could a non-root process to crash the whole server and OS? As far as I know FreeBSD is one of the most stable and reliable operating systems in this aspect..
Where could be the problem - the hardware, the OS or the software installed?
Any help is appreciated, thanks in advance!
