  Hello

  I am investigating this issue for you now, I will update this ticket shortly

1. Currently I am not seeing any issues with the server, nor am I having a problem accessing WHM or cPanel. I do however see that you have a high failcount for hitting the privvmpages limit on your VPS. This would definitely be a cause of the issue you are having. I would suggest talking to your datacenter about getting that limit raised as it’s causing issues with your VPS not being able to for the process for cPanel.

   Hello There,

   Kindly verify again.

   You will get these error finally even after being log in when you will try to open 3-4 links within cpanel.
   most probabally you will get these errors after login if not at login then may be after t=when you will browse any thing within cpanel. but that error removed when we refreshed that
   particular page.

1. Hello,I have verified Shawn’s findings and see that privvmpages is indeed a problem. As I’ve been investigating, I see privvmpages constantly increasing. This is causing the errors in WHM, and likely other services as well. You will really need to contact your hosting provider or datacenter to have them increase this limit, since this can only be increased at the host node of the VPS.
