If you have observed this behavior, please indicate which version of

EPICS base you are using. This would also be nice to have for my testing

efforts.

As a stopgap, I will build an event monitor into a future version of edm

which will watch for loss of event activity in some configurable manner

and at least notify the user.

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.
