Linux pcmonitor daemon stopped working

Hey guys,

I'm having this problem since a few hours ago. (5 to be precise). The dashboard and the mobile app notified me that one of the servers is offline. Went to check on it and it was fully operational, even though PcMonitor was saying otherwise. I tried restarting the daemon but no change. 3 of the server cores are at 100%.

Here is a screenshot from my webmin running processes.

if I run /etc/init.d/pcmonitor stop , the daemon is still running and the dashboard receives a "server shutting down" notification. I tried rebooting the server but the problem persisted.

I am thinking that some data got corrupted and pcmonitor has no idea what do to ... so it infinite loops.

I had the exact same problem and believe it or not, it turned out to be the July 1 leap second issue described here:

http://artipc10.vub.ac.be/wordpress/2012/07/01/leap-second-causing-ksoftirqd-and-java-to-use-lots-of-cpu-time/

I didn't figure it out until I was using Eclipse to build a plug-in and it was dog slow too. A bit of googling pointed me in the right direction. Hope that helps you!
