I'll focus on machine 'xyz' for now since its the one I care
most about:
Dell PowerEdge 1750 w/Dual 3Ghz Xeons and 3G of memory.
This thing idles most of the time as a mailserver for less than 150
users (both UW-Imap and SquirrelMail/Apache). CPU is typically less than
5% busy and top shows most of the memory inactive or free the majority
of the time. 'Sorry I do not have stats as of the time of the failure...
Don't have number of open files should be negligible (just *how* do you
get an exact count - I don't recall).
Output of netstat -m follows. Thanks!
