Description Joakim Sandstrom 2009-08-31 05:04:00 UTC 
This error appears on the rhq-agent once a week, so someone isn't freeing resources.

Temporarily adding the keyword "SubBug" so we can be sure we have accounted for all the bugs.

new = Tracking + FutureFeature + SubBug
Comment 4 wes hayutin 2010-02-16 17:04:38 UTC 
making sure we're not missing any bugs in rhq_triage
Comment 5 Corey Welton 2010-11-22 17:59:14 UTC 
Ian - what are your thoughts - is this a known sigar issue?
Comment 6 Ian Springer 2010-11-23 22:31:10 UTC 
I don't see anything like that in SIGAR jira. My guess is that this is not a SIGAR bug. There could be code in the RHQ Agent, PC, or plugins that is not closing files when done with them. We will need to do an audit of all that code to look for all R/W input streams or readers/writers are being closed.
