freebsd stable - Feb 2004 - 4.9 doesn't answer.

Hello,

I have one FreeBSD 4.9-STABLE server, that recently started to behave
strangely. It is respones all ping request and I can change between consoles
and the ftp and mysql server response (but I can't login).
In the last week, it happened three-times.

So, the apache, sshd, etc. doesn't answer. I can't login to the sshd
server.
And The CTRL+ALT+DEL also doesn't work.
There is not kernel panic and I couldn't see anything in the log files, only
the reset button helps.

Anyone met this problem?

Thanks,
Zsolt

I don't had this problem before, but for debugging purpose you should 
try to get serial access to this server. Then you can check why sshd and 
apache aren't responding.
Or you may connect Keyboard Video and Mouse and take a look onto your 
root console ...
There must be some messages ...

This behaviour sometimes happend to me, but it was always a DNS Problem ...

First thing to check is rDNS - make sure the box can resolve the IP addresses 
used to connect to it.  That's often why ssh/telnet/ftp/etc hang up -
waiting
for rDNS results to write log records.
