Hello

My colocated web server (running FreeBSD 2-2-6Release and Apache 1.30 (I
believe) just crashed and I have not been able to get in touch with my
system administrator.  I have been able to get the server back up and
running again by having my service provider log in at the console and
issuing the shutdown command and rebooting.  I have changed the root
password almost immediately after I have seen the system come back up.

Now my question is, since I can't find my sysadmin, where should I look for
the cause of the crash and to see if it was just a hiccup or a security
break or some sort of DoS attack?  I have checked last -50 and don't see
any logins for about 45 minutes before it crashed.  I have a cron job that
runs a system check and emails me the results hourly, it looks like I got
one right before it crashed with the following message in it:

ping: sendto: No buffer space available

I found out it crashed when my colocate company called and said it dropped
ping.  I was on the machine less than 15 minutes before they called so it
wasn't down for too long.

I also checked /var/log/messages and all I see are some standard ftp
messages (session closed, no transfer time out, etc..) right before the
reboot message.

The dmesg.today file is dated Oct 15 and doesn't have any helpful info.
ipfw.today is also dated Oct 15   I checked maillog and don't see anything
unusual there either.   The xferlog file shows only normal ftp activity
that I can see.

Can anyone be of assistance in identifying what might have happened?
