On my Fedora 15 FreeIPA server, I'm having some problems with

This is happening very frequently, I'm having to restart the dirsrv
process once an hour, otherwise people start complaining.

I experienced similar problems with FreeIPA 1, when I was using Fedora
14 and earlier, and had to regularly (also once per hour) restart the
dirsrv process. Could this be related?

I also noticed this:

There are updates in 'updates-testing' which I believe fix the above
issue, but I'm reluctant to install from a testing repo on my
production server, can anyone report any feedback on this?
The above bug does not cause a segfault.
What version of 389-ds-base are you using?
Please enable the collection of core dumps so we can debug the crash - see http://directory.fedoraproject.org/wiki/FAQ#Debugging_Crashes
Can anyone help me out?
