Fix Apache freezing

Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
This is a very small project, but it requires a good skills. I have a Linux VPS server (Ubuntu-10.04-x86_64) provided by Webfusion, with Plesk 10. All was fine until last week, when Apache server has started freezing.

It is happening in average 20-30 times a day.

I've installed restart BASH script, which is restarting Apache every time when it dies, but it is not a good solution of course.

The web installed on Apache doesn't changed too much and it is not likely that it is the source of problems.

There is nothing wrong in logs (only "Apache is being restarted... Apache restarted.. and so on")...

What I need is freelancer who will lead me to fix the problem. Unfortunatelly I cannot give anybody access to shell (there are really expensive data), but I can follow instructions...

Skills required:
Apache, Linux, Plesk, System Admin, VPS
