Memory Issues

[Daerious]

I have a server that normally runs at 140mb but recently i started getting some alerts about memory usage. From the charts shown in the account manager resource usage, my memory has been spiking up to over 256mb often, momentarily, and not really regularly. It is generally a big spike on the hour, a medium spike on the half hour, and a small spike on the 15 minute mark. I have ran a status script every minute for a day, and it shows no increase in memory at any given minute. Is there any way to determine what program is running that is doing this?

log into ssh and do a "top" just before the hour and look at it closely whilst it spikes to see what's listed?

also examine your cron log to see what was running at those times

I found it, thanks for the suggestions.
