My cPanel setup upgraded itself at approx 0500GTM (it is currently 1025GMT) and since then I'm seeing the following problems:
Is anyone else having similar trouble, or is it just me?
Is there anywhere else I can check for what might be causing load to show higher values than it should when the machine it idle?
My first worry was that the VM had been hacked, but as the problems seem to have started directly after the update (that is when I started getting the "service failed, restarting" emails I'm not currently thinking that this is the case. I don't think the unexpected load reading is due it UML as my UML kernel has not changed recently and has been running fine for months.
I've tried forcing a complete update of cPanel (in case something odd happened in the overnight update that left a problem a forced update would clear), making sure that the underlying CentOS is uptodate, and rebooting - all several times.
- The load reading has been constantly higer than usual, even though the machine is practically idle most of the time. Running top shows no process using anything more than a fraction of CPU time, in eith busy or io-wait states. /proc/io_status confirms that there is little IO going on and the load readings of the host machine confirm that there is little CPU being used. I'd notmall expect to see load readings between 0.2 and 0.5 on this machine except the occasional burst of activity, and it is currently constantly above 3.5 despite apparently no tasks doing anything.
- Some services keep failing, or at least the monitor things they do and keeps restarting them. This is usually exim and cpservd. Exim does seem to be running OK, as I'm getting the "service automatically restarted" messages to an external account.
- WHM keeps stopping responding to HTTPS requests on port 2087, which lends some credence to the messages that cpservd is stopping, but it doesn't stop responding to HTTP requests on port 2086.
- When poking arouns WHM over HTTP://<addr>:2086, the I keep seemingly getting logged out (so the browsers HTTP-Auth dialogue appears). Once I've re-authenticated I continue where I left off, but twice this has happened so many times in a short time that the brute-force detector blocks me for a few minutes.
