Problems with RHEL6 on Dell R810 "The canary thread is apparently starving"
I've been having some issues for awhile with a Dell Poweredge R810 running RHEL6 that I haven't been able to solve. This issue has been persisting since being setup and through all updates(just applied the 6.2 updates yesterday) and what I am seeing in the /var/log/messages are these lines repeating whenever the problem is occuring(server slows down to a crawl and all the VMs running on it as well)
Dec 7 08:52:11 gsr1 rtkit-daemon[4061]: The canary thread is apparently starving. Taking action.
Dec 7 08:52:11 gsr1 rtkit-daemon[4061]: Demoting known real-time threads.
Dec 7 08:52:11 gsr1 rtkit-daemon[4061]: Demoted 0 threads.
Any ideas?

I had same issue during few hour and checked log files, same log file as above. During that time one java process was showing up 690-700 % on top tool, not on ps output. Now the system is back to normal but really would like to know what was the cause.
