[Samba] samba slowing down

[Cj Tibbetts]

The longer our samba runs the more delayed the responses become. Samba has
been running for 5 months but this new development was noticed 2 weeks ago.
The first major sign of the issue was a new DC was trying to join and
failed due to timeout errors. At close look we see performance degradation
within a few hours or when we try to join a new DC.
