samba - Mar 2002 - NT_STATUS_INSUFFICIENT_RESOURCES ... why? (fwd)

I have been trying to track down this problem for a couple of weeks.

I'm running 2.2.3a w/ winbindd. Winbindd uses up all my sam connections
to my PDC until it maxes out the PDC. When it's max'd wbinfo -g etc
reports "Error looking up domain groups". I can not run the "User
manager for domains" on my PDC due to a "Insufficient system resources
exist to complete the requested service"

I only get it back by killing off the winbindd process and restarting
it, or by rebooting the PDC (not my preferred method). This lasts about
an hour or two before I have to kill winbindd and restart it.

I was encourage to see the post last night about a fix (below) that I
thought would address this problem. Unfortunately, after a make clean;
make install, the behavior still exists.

So I guess I'm reporting that the patch below to
samba-2.2.3a/source/nsswitch/winbindd_user.c does not seem to address
this problem.

OK here is a fix for the NT_STATUS_INSUFFICIENT_RESOURCES problem
in 2.2.3a.  Unfortunately it requires a patch and a recopmile.

The problem is not present in HEAD or (the yet unreleased) 2.2.4

Yeah!  Good catch :-)  Did you post this to Samba@samba.org
yet?  I didn't save the emails of the bug reports :-(

Aha so this is the flip side of the problem - running out of group handles.
I did try to test for this but couldn't reproduce it.  Hmm - maybe I
didn't try long enough.

Try this (untested) patch
