Is this a good measure? At least it's exact. :-)
# du -sh /var/log/httpd
261M /var/log/httpd
Those logs are rotated with default settings, 5 logs kept. The activity
went up recently, when a new, quite complex Wordpress site was launched.
That might have a lot to do with the crashes.

Many websites on that host use MySQL, yes.

Ok, I added RAM (remember, this is a VM). Now I got
Mem: 2365180k total
Swap: 3014648k total
This might help me some way. My experiences so far indicate that a
webserver/nameserver should be ok with 2 gigs RAM plus some swap. I am
not sure how much it depends on the amount of traffic.
