[clug] Help: Memory Evaporating!

[Alex Satrapa]

I have a problem with a web/database server here, and I'm not sure how 
to figure out what the problem is, much less solve it.

On my server, I have 1GB of RAM, and something is chewing it up at the 
rate of approximately 3kB/s. That something doesn't show up in process 
listings (ps auxwww sheds no light on the matter). My machine - for all 
intents and purposes - is having its memory swallowed up by the same 
Chinese dragon responsible for solar eclipses.

Does anybody have some clues as to where I could start looking for this 
lost RAM, and perhaps a means of recovering it (besides rebooting the 
machine)?

I'm running Apache, which is serving CGIs written in Perl that use DBI 
to access a PostgreSQL database.

I've restarted the big memory-using services on the machine, but the 
used memory didn't come back. Could there be processes still in memory 
that aren't showing up in top, ps or /proc/?
