First of all, check the information you have in the logs;
/var/log/security is a good point to start. Also check
the log files for services you run, maybe /var/log/maillog,
/var/log/xfer.log, /var/log/ftpd.log.

Also check if the services you run start exhibiting
strange behaviour. In case you notice _that_ - problems
have already started...
