About 2:10am tonite I noticed my linux box HD chugging away (I use it as
a server and was not using that system directly at the time). After a
few minutes I checked over to the console and it was showing out of
memory and killing processes. The box hadn't really have any problems
before. Any way to track down the issue? I'll post a log excerpt below.
The system's FC4, patched except for things the past few days, and
running some basic services.. dhcpd, named, ntpd, cups, and the standard
system services (sshd, autofs, crond, etc..). Actually, one non-typical
thing is it's running apcupsd to monitor a UPS. Any suggestions on what
or how to investigate what caused this?
Thanks,
Steve
