****************************************************************
An abend occurs which causes CICS to drive the recovery routine
of DFHFCVR. During the recovery the routine fails to release
the locks that it had acquired earlier for the write. This means
that the file remains locked, with further write and close
requests being queued. Restarting CICS is the only way to free
the lock.
