If the soft cancel abend happens to occur after the calling thread is resumed, DSNVEUS2's recovery will attempt to resume the caller again. This could result in the calling thread being resumed prematurely if it happens to be suspended waiting for its own updates to complete.

DSNVEUS2 has been updated to avoid resuming the calling thread twice during recovery.
