503 Service Unavailable on Lotus

[homerthingy65]

When navigating through our website at pncguild.net, and doing things such as posting threads, some users are being hit with this message:

"503 Service Unavailable

The server is temporarily busy! Please try again later." (I've changed the message to let everyone know it's ongoing and I'm trying to get help to fix it.

The issue doesn't seem to be for everyone, it's only a few. I removed a auto-posting plugin that might have been the problem since I saw that "some plugins that connect using scripts may cause that problem"

The problem is still occurring. Any assistance?

What does it show for you under your HTTP CPU Usage in cPanel? It may be using too much CPU at times and the process is killed.

Here's a screen of it:

I have this problem too.. It is happening more often these days..

I have checked my HTTP CPU Usage and its is well below normal usage..

The error occurs quite unpredictably... Sometime it happens, sometime it does not happen...
