samba - Feb 2009 - Winbind-Problem Samba 3.2.8 on AIX 5.3.9

Hi everyone,

On a newly installed AIX-LPAR (oslevel 5.3.9) we added the current samba version
3.2.8. Installation and configuration did not reveal any problem.

The problems show about 5 Minutes after services startup. After starting the
samba services the winbind daemon uses lots of CPU time and memory.
Wbinfo -u and wbinfo -g work after initial startup.

We cannot connect to any share on the machine. The level 10 log of the winbind
daemon start to show lots of the following messages:

Sending request to child pid 290960 (domain=FB6)
  talloc failed
  timed_events_timeout: 299/999828
  Could not receive async reply from child pid 290960
  fork_domain_child called for domain 'FB6'
  Could not receive trustdoms

The domain process went without any problem, the smb.conf was copied from a
3.0.26a system and adapted to reflect the new server name.

Config files and level 10 logs are available for smbd, winbindd and 1 client
system (that tried to connect) and can be provided.

Kind regards

Dr. Volker Arendt

Hi everyone,

We just took one step  forward. We changed the winbind entries for user
and group enumeration from yes to no and change the winbind cache
timeout to 60 seconds. That solved the talloc problem (or so it seems)

Will keep you updated

Regards

Volker
