I have seen the same behaviour and it annoys me, too. What I did in the past 
is a "cleanup" in ODBEdit which removes these open records. I have soem code 
in cm_watchdog(), which should take care of that. If a client is dead, it 
gets removed from the ODB, and its open records should get its notify_count 
decremented. So obviously this code has some bug. I plan to do in the 
following week (now I got some spare time) the following:

- exchange most db_create_record() by something better. Maybe 
db_check_record(..., correct_flag), which creates the record only if it does 
not exist at all, otherwise checks the structure. If correct_flag is TRUE, it 
corrects the strucure (by calling db_create_record()), if it's false it just 
returns an error code. This way one can decide from case to case which option 
is better. Like for the /Runinfo, the flag would be FALSE, maybe with a 
notification that the /Runinfo is different from the compiled-in structure, 
and one hast to recompile the application.

- revisit the open record issue from dying frontends. I remember vaguely that 
I tried to kill a frontend (kill -9), wait until the watchdog cleans up its 
entries, and it worked fine. So it's more the problem to reproduce the issue 
described in the previous elog entry.
