A possible solution was posted to fix the MiqServer: https://bugzilla.redhat.com/show_bug.cgi?id=1535720 After applying this locally, it has brought a lot of the memory instability under control, especially with the C&U Metrics Collector. The jury is still out with the GenericWorker. So I'm diving into that at this time.
Himanshu, The patch that went in reduced most of the leaks I am seeing in the various workers. Would you please retest with the latest and confirm you still see it? Thanks
The source of this issue was a leak in Ruby "require" which was found while investigating a leak in Miq Server and has been fixed under BZ 1535720 *** This bug has been marked as a duplicate of bug 1535720 ***
