------- Comment #60 from jhyder79 at gmail.com 2008-01-11 07:40 CST -------
I have been trying to make winbind hang to the point I could capture some data
from it since my last post and it finally happened this morning. I am having
the exact same issue that I had in my original request for help, but this time
I am not getting the "winbindd: Exceeding 200 client connections, no idle
connection found" message in my logs.
This morning I was trying to browse our Linux file server and it just stopped
responding to requests. I dug around and found out which winbind process was
attached to my userid and ran strace. This is the output I got:
[root at dtlinux ~]# strace -p 16568
