Re: [Freeipa-users] Process open FD table is full.
Thanks, I can't view the bug either but I'll pass it on in my support case. Erinn, in case it helps my support case # is 00646841. Oh and sorry for the mail formatting, Outlook at work...

Re: [Freeipa-users] Process open FD table is full.
Looks a lot like a problem I have as well. Check out the /proc/xxx/fd directory of the dirsrv process for your IPA realm, in my case it's full of dead pointers to /var/tmp/ldap_xxx where xxx will be the same on one IPA server(I have two in a multi-master setup). These don't clear out until I restart the dirsrv process, so eventually they'll fill up to the FD limit.
