Why Outbound Campaign stop dialing? See message WAITING_RECORDS, but there are retrieved records.
After stopping the campaign, records have same status (retrieved)

I have observed records get into a stuck state sometimes (usually do to user error / manual intervention in some way).  This being said, if your records are still showing as retrieved after the campaign stops - they shouldnt be.  After stopping the campaign, either set those records as ready or remove them.  I believe OCS won't actively try to add records of type 'retrieved' into OCS buffers for dialing.  Things explains why you see WAITING_RECORDS.  Make sense?

'I believe OCS won't actively try to add records of type 'retrieved' into OCS buffers for dialing' - uh? Records in 'Retrieved' status are in OCS buffers.

You either have stuck records or simply the records in your calling list cannot be dialed are not in the 'select' criteria, e.g.out of from / to time window, personal callback where the agent is not there, not in the dialing filter etc.
