Re: amazingly, debian server keeps crashing
I had exactly the same problem (albeit with different hardware) for about a
month. But I was running Exim and it was Exim that was (apparently)
generating the error.
Someone suggested I tried another stick of RAM.
I took the RAM out of a working machine and stuck it in instead.
Took the now redundant RAM, stuck it in a other machine, ran memtest86 and 2
days later - memtest reported an error.
Six months later - the mail server had not failed once!
I would suggest you look at this first - mainly 'cos it's cheap!
