100% CPU SPIKE > POSSIBLE FIX

Postby danfloun » 08. August 2007 21:13

Well after lots of wasted time I finally found what was causing my Apache service to spike to 100% CPU.

By the way, I'm running Windows XP Pro x64 but it probably isn't relevant to this issue.

It wasn't any of the following:

Firewall (XP)
Anti-Virus (AVG)
Ad-aware 2007
Xampp Control Panel

Fixes tried:

Adding Win32DisableAcceptEx in httpd.conf stopped the Apache service loading.

Reinstalling didn't help

I also tried WAMP 1.7.0 & 1.7.2 with the same outcome.

I finally realized what it was when looking through my add/remove programs.

'Diamond PortExplorer'

A windows port explorer which I had only installed a few weeks back.

Not sure why this happened but removing it fixed the spike.

So, if you have any port scanning/exploring tools or other network tools you should remove them if you are having similar problems and you have tried the above Win32DisableAcceptEx fix.

Hope that helps someone.
