2) There is a more subtle ongoing problem that (as far as I know) has

only been reported here at Jefferson Lab. When an EDM session has been

left running for a long (variable) time, the widgets will stop updating

despite the fact that the PV values are still changing. There is no

visual clue that anything is wrong, unless you can see the same PV's in

a different app or a separate EDM session. Usually everything will start

updating again if you open or close a display, or even expose a covered

display. This issue only started when we moved from HP-UX to RedHat

Enterprise Linux. It has not yet been resolved.

We here at the UW Medical Center have also seen this behavior, running EDM on

Debian Linux.
