[Samba] My god, it full of "CLOSE_WAITS"

[Tim Laurence]

Hello samba people. I am having a odd problem related to winbindd. 
When I leave it running overnight on a quiet (not silent however) 
server I find that it generates a large number of CLOSE_WAIT state 
connections. 84 on a fairly quiet system in the last 18 hours. I 
can't seem to find any command that directly affects the number of 
CLOSE_WAITS. Below is my netstat listing. Any ideas would be helpful. 
I looked around but could find no reference to this problem. I am 
running in SECURITY = ADS mode. Thank you everyone for help.
