I have a problem where certain pages will not load. They seem to load for 36 seconds, and then boom.. 503 error and this in the logs:

I am running CloudLinux with limits 1 full CPU core and 1024MB RAM, so don't think that is the problem. In LiteSpeed, soft/hard memory limits are not set for the external application.

Any advise?

I already tried to increase the Initial Request Timeout.

For what it matters, this error only happens after I enabled the "Flat Catalog Category" feature on a Magento site if you are familiar with it. The CPU of the lsphp5 process stays on 100% and then the application crashes after 30-40 seconds with 503 error. No other error in stderr.log.

I already contacted CloudLinux and they say it is a Litespeed issue.

I'm getting this problem but with rebuilding attachments in XF. The seconds it takes to throw the 503 changes. Anywhere from 70-300 seconds. My IRT is set to 300. So why would it crash at say 70?
