used physical memory 98%

[maica]

Hello all, I run a small IT service company in Japan and my systems engineer who setup my web server was deported back to russia on false visa documentations... my knowledge is little on linux server and was wondering if anyone would be intrested in helping for a fee.
I have a redhat server with plesk 7.5 dual xeon 2.4 cpu and 2gb of ram . i have been experiencing spam attacks on some of my domains in the server and i don't if it's related or not but the sever runs out of memory especially on the weekends. I am looking to upgrade the memory to 4GB but i have this feeling that it's going to be maxed out unless i figure out this problem. I was wondering if anyone had problems similar to this?

Well, this command will not identify definitively which processes are consuming the most memory -- but it is a good start:

ps -eo vsz,pid,comm |sort -n -r |head -25

The problem with vsz (virtual size) is that it adding up the values you will double count shared text pages and IPC shared memory. But it should be "reasonable".

Thanks but how will i run the command....?
I'm looking at my running processes in webmin and i keep seeing one of my hosting blog sites eating up about 100mb of ram. The site is reciving spam posts and i can't figure our how to stop it. thanks for your time.
