I'm not sure that will help, that is pretty much what was happening
before.  The key is to send a -HUP to the whole process tree to make
them re-open the logs, otherwise the other child samba processes will
still just write to the .old 

I know this sucks.  I think the solution is to have a new reopen-logs
message created so this can be used in logroate, and to have it used
internally as I mentioned.
