I just got a new server and When attempting to update cPanel I got this:

Hidden Pid detected! [pid 6456]
hidden from ps: [yes]
binary location: [/usr/sbin/named]

Rebuilding Process List...Done
Hidden Pid detected! [pid 6457]
hidden from ps: [yes]
binary location: [/usr/sbin/named]

Rebuilding Process List...Done
Hidden Pid detected! [pid 6458]
hidden from ps: [yes]
binary location: [/usr/sbin/named]

Rebuilding Process List...Done
Hidden Pid detected! [pid 6562]
hidden from ps: [yes]
binary location: [/usr/bin/stunnel-4.04local]

Is this OK is there something lurking on my new box?

No worries! This is a known bug in RHE cPanel servers running the "Stable" release. The good news is that is has been resolved in the "Edge" release.

Take care...

Thanks sir..... Now I won't lose sleep
