[Freeipa-users] dead in the water IPA server

Sun May 13 21:36:36 UTC 2012

Hi,

I have what I'm told are 6.3 rpms on ipa2 and no its not fixed, the memory leak kills a server in 48 hours.  I also find I have a problem with rebooting, IPA doesnt survive a reboot, so I cant even cron a reboot nightly.

Right now both are in a bad way and I need to reboot them......

:(

The interesting thing is I have a test setup that is stable, yet has the same rpms....so Im flumixt'd, maybe its something Ive done, but I cant think what....its bod standard as far as I know....

Hi,

Yes I have a memory leak see attached graphs....

Yes looks like the killer killed slapd.......dont know what caused this yet........if its the "killer" looks like its decided to kill slapd or slapd was going to kill the system anyway so it may have done the right thing.

Looks like I have 3 days between reboots if i dont IPA losses the plot big time....very bad news..........I will I think slow IPA deployment here at this time........this cant be deployed for us as it is, I cant even test as if something doesn't work I don't know if its my configuring error or an inconsistent IPA.

:/

Thanks for this info I will pursue this through RH support for a perm fix, adding more memory doesn't strike me as the solution, 4gb of ram for 3~4 users and about 6 client machines seems a lot.....

Right.  See https://fedorahosted.org/389/ticket/51 and especially all of the comments to https://bugzilla.redhat.com/show_bug.cgi?id=697701

You will need to closely monitor your entry cache usage.

As far as I see the ticket is fixed upstream and is in testing for 6.3.
Is this the correct understanding?

This sound very much the same as the issue I've been having. Did you check to see if it was the
directory server that consumed all of your memory too?

Hi,

It seems that your system ate all the available memory and the kernel
decided to kill a directory server instance to free some. The kernel agent responsible for this is
called the out-of-memory killer, you can read more about it and how to configure it not to kill
important processes here: http://lwn.net/Articles/317814/

I take it it isnt good?  cant login that is for sure so whatever is behind the web gui is dead
if nothing else...
