Compare config with multiple targets gets "263: Error 1 sending version to client" (4220012)

When running compare config with multiple target routes, compare server has the following error

"263: Error 1 sending version to client"

and target server post queue backlog increasing

and target var dir/state directory have many *lock* files

Product Defect, issue caused by reader sending multiple Deq marker messages to each target

STATUS:

This issue will be fixed in future GA update after 7.5.2.50.

WORK AROUND:

1. Cancel compare on source, kill *desvr* processes on source and *declt* processes on target if necessary.
2. On target, stop post
3. go to vardir/state and remove *lock*
4. If post still get stuck, then contact support to remove compare marker records in the queue
5. Start post
