Bob,

I had a thread with you a while back about the session timing out and
closing my connections.  I found that by killing xscreensaver the
problem went away.  The problem started after running a patch bundle
in.  I have recently discovered that the problem appears to be in my
".xscreensaver" file.  I noticed that a new user I created did not
experience the same issue.  Their sessions never "timed out".  I moved
their .xscreensaver file over mine and my problem cleared.  I have
compared the 2 files and do not see any major differences, other than
the screensavers I disabled in my file.  (Not sure about all that's in
the file though)

Might this be a similar issue?
