    I have just barely installed cPanel/WHM VPS Optimized and got this email:

    Does this mean that cPanel deleted necessary and important system files? Is this a bug in the current distribution? I am testing out CentOS 6 x86_64 with the latest cPanel WHM VPS Optimized on this specific system. I wonder if it has to do with cPanel and an incompatibility with the Linux 3.0.4 x86_64 kernel.

    Those are likely false positives. Too investigate further please use lsof with the p switch and the pid in question as the argument so we can have more information to investigate. Also a ps auwx would not hurt. If you cannot investigate with that info please past them here or on a pastebin so we can assist further.

    I'm going to switch my kernel back to 2.6.x from 3.0.x and see how things go.

    After switching back to the 2.6.x kernel, I haven't had any more issues. It seems to be a compatibility issue using cPanel, CentOS 6, and the 3.0.x kernel (which wasn't a native part of CentOS 6).

    FYI this wasn't a production machine, just a testing machine.

    Yes, I am. Is there anything I should know about cPanel and the Kernels they provide?

    It looks like with the thread you posted, that they have identified the issue as a problem with the Perl module. (Post as of 11/11/11). Would this be a fix that could be implemented by cPanel?

    While many customers use custom kernels without issue, cPanel is tested on standard kernels. Using a custom kernel increases the chance you will encounter problems with cPanel. If you continue to experience this issue, feel free to submit a ticket to our staff for further review:

    Thank you.
