We use a dual P11 300 w/256K memory, Intel 10/100 network board for our
primary mail server. The machine is for mail only and no other programs are
running on it. We monitor all of our equipment with IPSwitch's What's Up
Gold and on the mail server it is monitoring services POP3, SMTP, HTTP and
IMAP.
Since Saturday, SMTP has been bouncing up and down seven or eight times an
hour. What's up polls ever 60 seconds, and usually, SMTP comes back up
before the next poll, but not always. Frequently, all services will shut
down, and come back up within 60 seconds. The processor does not show any
particular increase in use during these times.
Our load has not increased. Logs show the same amount of mail, 28,000 to
35,000 msgs per day depending on the day of the week as it has always been.
The ONLY thing I have done (last Friday) is add some rules to the rules.ima
and some lines in the kill file. I don't think that would cause SMTP to go
down.
Any ideas why SMTP and other services started shutting down or have I just
out grown the size of my mail server?
