[Samba] winbindd completely stopped responding

[Gaiseric Vandal]

idmap and winbind may be caching the entries (use "testparm -v" to look 
for cache or timeout values.)   windbind or idmap processes may load 
data when they start, cache it, but when the cache expires  they DON'T 
reload the data.

Just a guest.  I had this problem with samba 3.0.x but not 3.4.x.
