RTDBAdapter is missing SCADA digital inputs after an idle system alarm has been generated

The RTDBAdapter configured to generate a system alarm if no data is processed within a configurable amount of time using the -idle option.

If a system alarm has been generated (due to not receiving data) and then new data arrives.  An alarm gets generated saying that processing has resumed but DDService does not seem to process the incoming digital values
Note: this testing is being done by sending in phase operations on the same device.

E.g. Send in an open on Phase A... see the entries in the DDService log for the open.. then wait until the "no data" alarm is generated... then send in an open on Phase B.    There are no entries in the DDService log for the phase B.

Normally, when RTDBAdapter processes a row from scada_digital_in I see the following in the log:
05/28/20 10:45:23: 0x7f3602674700,ctp=0x1a22e98,"readDigIn" readDigIn: scada_digital_in - numFound=1
05/28/20 10:45:23: 0x7f3602674700,ctp=0x1a22e98,"readDigIn" readDigIn(1) - processed by DDS:
  Analog =0
  Status =1

However, in this case I am seeing:
05/28/20 10:46:26: 0x7f36026b5700,ctp=0x1a22e98,"readDigIn" readDigIn: scada_digital_in - numFound=1
05/28/20 10:46:26: 0x7f36026b5700,ctp=0x1a22e98,"readDigIn" readDigIn(1) - processed by DDS:
  Analog =0
  Status =0

The open should be getting processed on phase B.
