My Samba server has slowed down dramatically since yesterday afternoon, although I'm not seeing any obvious signs of issues occurring in the smbd.log or in messages.log. Load average is low and there is plenty of memory left. Also, OS X clients are getting logged off at random intervals and I'm finding this message in the individual samba host log files which is my only clue as to what is happening. smbd/service.c:close_cnum(841) Any ideas anyone? nick
