Hi This has bug has pretty much destroyed my IPA deployment.......I had a pretty bad memory leak had to reboot every 36 hours...made worse by trying later 6.3? rpms didnt fix the leak and it went split brain........2 months and no fix....boy did that open up a can of worms.....
:/ In my case I cant see how its churn as I have so few entries (<50) and Im adding no more items at present....unless a part of ipa is "replicating and diffing" in the background to check consistency? I also have only one way replication now at most, master to replica and no memory leak shows in Munin at present......... but I seem to be faced with a rebuild from scratch....... regards Steven Jones Technical Specialist - Linux RHCE Victoria University, Wellington, NZ 0064 4 463 6272 ________________________________________ From: freeipa-users-boun...@redhat.com [freeipa-users-boun...@redhat.com] on behalf of Sigbjorn Lie [sigbj...@nixtra.com] Sent: Tuesday, 5 June 2012 7:14 p.m. To: Rich Megginson Cc: freeipa-users@redhat.com Subject: Re: [Freeipa-users] 389-ds memory usage On Mon, April 23, 2012 20:38, Rich Megginson wrote: > Ok.

See below for an output of the memory usage and the current size and hitratio of the cache on the 3 production IPA servers. How do you suggest moving forward to troubleshoot this issue?
