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.
