Something eating up my RAM and Swap

I need urgent help troubleshooting this problem:

My server strated acting up today, I updated to 3.56 over the weekend..

Twice today, the server is almost to 120.00 load average, it lasts about an hour then goes back to normal.

Webmin/Virtualmin die completely, I have to restart webmin after the server is back to normal.

right now it is at 100.00+ load, with 30+ zombie processes

Dual zeon, 2gb ram, 1gb swap -- all used up

Very hard to get any info from the server as it is having problems, because I cannot access it.

Status: 
Closed (fixed)
