[Samba] Streaming large videos causes server's networking to crash

[Paul Accisano]

That link certainly sounds promising.  I'll try to induce another crash 
after trying the things you specified and see what happens.  I really 
appreciate your helping me even though this is looking like it's not 
even Samba-related.

Your "tsk tsk" implies that posting one of those logs was a security 
risk.  For the sake of learning, which log should I not have posted?
