Hi Ralph,

Some more tests I've done indicate that locking is only working between 
2 of my 6 VIPs (one per host). If I open a file on either of these two 
"working" hosts, it's locked on the other working one, but not on any 
others. Opening a file on any of the "non-working" hosts means the file 
is not locked anywhere else.

On my test setup with only two nodes it seems to work normally with both 
4.4.5 and 4.4.6.

All hosts have the same smb.conf.
