login to WHM and click on Apache Status.

that doesnt help too much, there are lot of different sites over there that change everytime. There isnt exactly one that appears all time.

This started when I updated to latest release version WHM 11.2.0 cPanel 11.11.0-R16983.
Anyone is having some issue with this release??
