[cobalt-users] RaQ2 Server stops responding, any ideas?

["Ali & Charlie" <dynamicduo@xxxxxxxxxxxxxxxx>]

One of our RaQ2s keeps becoming inaccessable for ftp, email and http access
for no apparent reason. This is happening on a daily basis, usually in the
morning and we cannot figure out why. The server is not under a heavy load
as can be seen below, and after awhile, it will begin responding again as
normal.

  4:49am  up 22:32,  1 user,  load average: 0.05, 0.08, 0.06
45 processes: 44 sleeping, 1 running, 0 zombie, 0 stopped
CPU states:  8.2% user,  2.2% system,  0.0% nice, 89.7% idle
Mem:   63400K av,  50436K used,  12964K free,  34188K shrd,   1472K buff
Swap: 130748K av,     76K used, 130672K free                 30004K cached

We can login to the machine and then reboot it and it begins responding fine
again. Where should we begin looking for the problem here?

Thanks,
