Winbindd in HEAD: cannot deal with 15,000 users+

[Mike Papper]

I have run the latest winbindd from the samba-3.0-alpha17 branch. I ran it 
for the past 4 days and all went well. However, in the following situation, 
it breaks down... If I have 15,000 users, its OK UNTIL I add or delete a user 
from the set of 15,000 users on the PDC. It seems like any update to the PDC 
causes winbbind to fetch all the info from the PDC (and not just the 
updates). This seems to make winbind crash. When I bring winbind back up, it 
runs OK until I once again add or remove a user from the PDC.

I am using NT 4 service pack 5 as the PDC. Any thoughts on why this could be 
happening? Or thoughts on what this debug output is saying?

Also, I did send a bug report to samba at samba.org as suggested in the release 
docs). Will this bug report get into the right hands?

Heres some log output from winbind (set to log level 3):
