[Samba] samba getting stuck, highwatermark replication issue?

[mj]

Dear Andrew,

Your explanation makes a lot of sense, thank you. Alo for the 
clone-dc-database tip.

Really no need to end your email with "Sorry", your presense and advises 
here are very much appreciated, and as I've said before: Thank you for 
your hard work on making samba what it is today!
