samba - Nov 2008 - File lock recovery

Hi,

I am having some issues with lock recovery.

If a client gets powered off after acquiring an exclusive lock on a file,  the
Windows server  grants the file lock to a second client within 2 minutes.
However, the Samba server (version Samba 3.0.28-0.el5.8) that I am having does
not look to be detecting the dead client and so, a second client is not getting
the lock on the same file even if it waits for >30 minutes.

Is it (no resource recovery) an expected behaviour? Is the resource recovery
time is something that can be configured? Can the option "reset on zero
vc" be useful in such a situation?

Thank you in advance for your help


Thanks and Regards

Sudheer

Replying to my own post. I got it working by using  SO_KEEPALIVE option in
smb.conf and tuning keepalive proc variables. Please let me know if there is a
cleaner way to get the same result.
