Hi
We're running a new Unixware 7.1.3 Server (Update pack 3), and it is running SCO MailServer in the Linux LPK. There's 1GB of RAM.
It's using fetchmail to retrieve mail from our ISP's POP3 mailbox, running as a daemon with a 5minute poll interval.
We've just gone live, but we've had a couple of problems where the Outlook PCs can't connect to the Mailserver. I wasn't on-site the first time it happened, but someone rebooted the server. I've been monitoring using rtpm, and I see that the %mem and %swp values are steadily increasing over time. After a reboot, they were at 17% and 9% respectively. Three days later they're at 71% and 46%. The second time the server crashed, they were at 73% and 95%, and after the POP3 server failed to respond, the entire server fell over (running a 'ps' command gave an 'unable to allocate memeory' error).
I'm fairly new to Unix, and am not sure how to go about finding what is eating the memory, and how to fix it.
Thanks
David
