Memory Leak?

deranjer · 01-23-2013, 07:17 PM

I have an issue with my home server locking up, when I check the monitor the memory is completely used. I can restart the server and slowly over about 5 days or so it goes all the way back to full (2Gig) and locks up again. I'm not sure how to figure out what is causing this.

I believe that if I kill the process I should get the memory back?

So I killed every process I don't think is essential, however still have the memory issue. Still using 1.7 Gigs with barely anything running... how do I figure out what is causing this?

Code:

I think its saying you have 2GB of RAM and no swap (you could use 'top' to get an alternate view).
You may be running too much SW for that much RAM.

Well I killed even more processes.. If the process isn't running won't it release the memory? Because I only have a couple of things running, AND when I start my server it runs for days before the memory gets critical..
