Error description
The CICS region took abend0C4 's in DFHTSPT offset x'92E' during a SOS for below the line UDSA storage. The abend0C4s are occurring for tasks that are trying to RETRIEVE data from DFxxxxxx queues. DFHTSPT is processing a GET_RELEASE_SET request, and fails on a MVC instruction (D207 F000 AC7E) with Reg15 containing zeroes. This instruction is trying to copy the >TSIOA eyecatcher into SET storage. The SET storage should have been acquired from an unconditional GETMAIN in DFHTSPT. . It appears that the GETMAIN for SET storage failed, probably due to the task being timed-out while waiting for storage. But DFHTSPT issues a Lock Manager call to regain the TS lock before checking the response from DFHSMGF for the GETMAIN. The Lock Manager call uses the same parameter list as the GETMAIN so would overwrite the GETMAIN response. .

Problem summary
**************************************************************** * USERS AFFECTED: All * **************************************************************** * PROBLEM DESCRIPTION: DFHTS0001 0C4 exception in DFHTSPT. * **************************************************************** * RECOMMENDATION: * **************************************************************** CICS was short on storage. A started task issued an EXEC CICS RETRIEVE command to retrieve the FROM data passed to it by the START command. Interval control called temporary storage to return the data. DFHTSPT issued a conditional getmain to acquire set storage to move the temporary storage data into. This failed with a reason of insufficient storage. DFHTSPT then called lock manager to release the domain lock, before calling storage manager to perform an unconditional getmain. This could time out or be purged. However, DFHTSPT then called the lock manager to reacquire the domain lock before analysing the response to the storage manager call. Since DFHTSPT is defined to use the same area of automatic storage for lmlm_parms and smgf_parms, the response and reason codes from the getmain were by now overwritten by those from the lock manager call. DFHTSPT interpreted the response as being one of smgf_ok, so attempted to move data into what it thought was the storage area from the getmain. Since no address was returned, this tried to move data into low-core, and a protection exception / abend akea took place.

Problem conclusion
DFHTSPT has been changed to define the storage for lmlm_parms as separate to the union of plists used by its other domain calls.
