I had this problem.  I tried setting the SO_KEEPALIVE socket option in
smb.conf, but this seemed to have no effect, so I set keepalive = 30 in
smb.conf which works great, the smbd closes itself down after a minute or
two of the client machine crashing.

Should this be a default option, or should its potential usefulness be made
more obvious in the documentation.  FYI I am running 1.9.18p8 on Solaris
2.5.  With Win 95 and NT it is not uncommon to have clients crash on you :).

Cheers, hope this helps,
