The archiver is not failing to receive events. My interpretation
of archive data was incorrect. It appears that when a PV disconnects
the archiver generates data but when the PV reconnects no data is
generated when the PV value did not change. This results in the
following:
07/23/2001 04:49:10.000000000 OFF Repeat 19731
07/23/2001 04:49:15.009771252 ON
07/23/2001 15:13:40.000000000 ON Repeat 3747
07/23/2001 15:13:48.706195000 - Disconnected
07/23/2001 15:51:59.035355000 - Disconnected
07/23/2001 15:55:48.541504844 ON
07/23/2001 16:39:00.000000000 ON Repeat 260
07/23/2001 16:39:01.606623000 - Disconnected
07/27/2001 13:20:06.997712000 - Disconnected
07/27/2001 13:55:14.999999800 OFF INVALID UDF
07/27/2001 20:06:40.000000000 OFF Repeat 2229
07/27/2001 20:06:45.015774866 ON
07/27/2001 20:07:50.000000000 ON Repeat 7
So, using the LibIO API, if I ask for data prior to 07/27/2001 13:20:06 I
may get a record which is again invalid. One therefore must keep going
back until a valid record is obtained.
I would argue for the generation of a data record when the PV reconnects.
