Error description
Your CICS region hangs due to a loop in module DFHFCRO. The loop can be seen in MVS system trace. The loop occurs under the CFQR task while trying to close and deallocate a dataset. The loop proc DFHFCRO_REMOVE_FILE_FROM_OPEN_CHAIN while trying to remove the file from the chain of Open RLS ACBs. . The problem started earlier with a DFHFC0001 0C4 that occurred during a call to deallocate the dataset. After the 0C4, the file being closed was left on the Open RLS ACB chain. The next time the file was opened, it is added to the RLS chain again. And during a QUIESCE of a dataset, CICS goes into a loop since the file is on the open ACB chain twice. .
