samba - Nov 2012 - smbd daemon crash when connect to shared folder

Hi All,

I've installed and configured Samba 3.5.11 on a Solaris 8 machine. I was
able to join it to the 2008 R2 AD. However, its smbd daemon is crashed everytime
I connect to its shared folder from the windows machine, so I'm not able to
connect to its shared folders. Below is its log from smb.log file. Is there
anyone has any idea what cause the problem? I appreciate very much

Regards,

Anh

Almost certainly too many groups for your poor Solaris 8 machine
(which has a limit of 16 groups per process I believe).
