[OpenIndiana-discuss] CIFS domain controller "not responding" errors

[Bryan S. Leaman]

I have a CIFS share set up on oi_151a, and it's working fine except that 
during times of sustained activity I get the following errors in 
/var/adm/messages frequently, every 3 to 5 minutes.  I also noticed that 
if I keep the share idle for awhile, then run a "dir" from a mapped 
client, it hangs for 5 to 10 seconds and when it displays the directory 
listing I get the same set of errors in /var/adm/messages.  After this 
happens once, then it's fine for some time with no delay on the client side.

I've copied hundreds of gigs of data to this share with robocopy without 
any failures on the client side, but something seems to be broken 
somewhere.  Any ideas?
