Yes I understand, however, there are 2 things I am concerned about.

When the errors are spewing, winbind never goes to sleep and the load on the
server runs somewhere between 6-8 constantly (as shown by top.). Even when
there is no one in the office and hence no files being served I still see the
high load.

When the errors stop (This happens intermittently) winbind will sleep and the
load settles down to < 1.

The other thing that concerns me is that I am wondering if this is an
indication that something more serious is about to break. It is one thing
for me to see things in the background and entirely something else for it
to impact the users. :-)
