I have a samba server that has been running for quite a while, without any
problems. Last week, out of the blue, everybody lost connections. I restarted
winbind and samba and all was well. It happened again, and again all it took was
a restart. It happened over the weekend then again on Monday, when I noticed
winbind was gone and just restarted that. When i happened again today I looked
into why.
Winbind is dying with an internal error. Here's what it looks like in the
messages file:

Since this is a daily occurance, its rather annoying, for me and the users. Of
course my boss wants to know why this is suddenly happening on an otherwise
stable server (I'd like to know that too).
I'm running Samba version 3.0.20b-2.1 on Red Hat Enterprise Linux ES
release 3 (Taroon Update 7)
