[Samba] Samba 3.0.21a panic - oplock problem?

[Andrew Morgan]

I upgraded from Samba 3.0.20 to 3.0.21a last night on my Solaris 10 
machine.  After the upgrade, everything seemed to work fine, but I see 
that Samba is panic'ing in the logs.  As far as I can tell, the client 
retries whatever it was doing and succeeds (at least, we've had no reports 
of problems from our users).

I have attached a level 10 debug, backtrace, and my smb.conf.  The 
commented out lines in smb.conf are what I used to generate the level 10 
logs and backtrace.

I will probably downgrade to 3.0.20 tonight, so please let me know if 
there is any additional information needed.

Thanks,
 	Andy
