Crashing Zones - Please help!

[swish]

Hey guys,

I recently had a problem that causes my static zones to crash.
I dont really know whats causing it but my guess is an overload.
I use dmg101. Since it started crashing I look on top (cpu status) from time to time to see hows the memory going. Sometimes it goes down and down and crashes but sometimes it doesnt go down much and crashes. I remmember once it crashed with 200mb memory out of 512.
Sometimes it crashes with not too many players but most of the time it crashes when i have like 17+ players. I cant say for sure, cause I reached around 26 players untill it crashed.

I was thinking to upgrade the computer but I talked to Aza77 and he is not sure that its crashing because the cpu's lack of memory. He thinks the server is not installed correctly or there is a DB issue (correct me if iam wrong Aza).

Is there a way to determain what was causing the zoen to crash ? In the logs somewhere ?

This is really important.

Many thanks =D
Swish.
