This looked odd to me. I find "sysstat" http://pagesperso-orange.fr/sebastien.godard/ package with it's "sar" commands and crontab jobs very handy to collect information and analyze it later. I run Debian on servers so for me simple "apt-get install sysstat" and afterwards modifying "/etc/default/sysstat" to allow for data collection is sufficient to get files in /var/log/sysstat. Then wait for system to misbehave and start analyzing data with "sar" command. Whatch out for memory consumption and where does CPU spend most of the time?
