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

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.
