CURSOR Keeps Closing

I wrote a stored procedure that contains some COMMIT logic, but keep
runnign into an odd problem. As soon as the procedure gets to the
COMMIT statement, the CURSOR closes. Here's the procedure:

CREATE PROCEDURE AIM.UPDATEARCHIVERETRIEVALSTATUS ( )
SPECIFIC AIM.UPDATEARCRETSTS
LANGUAGE SQL

P1: BEGIN
DECLARE RECORDCOUNT INTEGER;
DECLARE intLOOPS INTEGER;
DECLARE intImageCount INTEGER;
DECLARE decArchiveRetrievalID DECIMAL (13,0);
DECLARE AT_END int DEFAULT 0;
DECLARE NOT_FOUND CONDITION FOR SQLSTATE '02000';
DECLARE UPDATE_CURSOR CURSOR FOR
SELECT ARCHIVERETRIEVALID FROM AIM.ARCHIVERETRIEVAL WHERE
ESTIMATEDRESPONSETIME < CURRENT TIMESTAMP --AND EXPIRATIONDATE <
DATE(CURRENT TIMESTAMP)
AND STATUSID = 2
--OR SELECT ARCHIVERETRIEVALID FROM AIM.ARCHIVERETRIEVAL WHERE
OR
ESTIMATEDRESPONSETIME < CURRENT TIMESTAMP AND EXPIRATIONDATE IS NULL
AND STATUSID = 2;

DECLARE CONTINUE HANDLER for NOT_FOUND
SET AT_END = 1;

SET intLOOPS = 0;
SET RECORDCOUNT = 0;

OPEN UPDATE_CURSOR;
FETCH_LOOP:
LOOP
FETCH UPDATE_CURSOR INTO decArchiveRetrievalID;
SET intImageCount = (SELECT COUNT(IMAGEFRONT) FROM AIM.AIMRETRIEVEDITEM
WHERE ARCHIVERETRIEVALID = decArchiveRetrievalID
AND LENGTH(IMAGEFRONT) > 0);
IF AT_END = 1 THEN
LEAVE FETCH_LOOP;
ELSEIF intImageCount = (SELECT ITEMCOUNT FROM AIM.ARCHIVERETRIEVAL
WHERE ARCHIVERETRIEVALID = decArchiveRetrievalID) THEN
ITERATE FETCH_LOOP;
END IF;
UPDATE AIM.ArchiveRetrieval SET STATUSID = 3 WHERE ARCHIVERETRIEVALID =
decArchiveRetrievalID;
SET RECORDCOUNT = RECORDCOUNT + 1;
IF RECORDCOUNT = 10 THEN
COMMIT;
SET intLOOPS = intLOOPS + 1;
SET RECORDCOUNT = 0;
END IF;
END LOOP FETCH_LOOP;
CLOSE UPDATE_CURSOR;

CALL AIM.UPDATEAIMRETRIEVALSTATUS_CRON();

END P1

For instance, I know there should be 45 rows updated. The procedure
gets through the first set of 10 updates and then it bombs and gives me
the following error:

A database manager error occurred.[IBM][CLI Driver][DB2/6000] SQL0501N
The cursor specified in a FETCH or CLOSE statement is not open.
SQLSTATE=24501

Can I assume the COMMIT is what's causing it to close the cursor? Is
there any way to address this?

THanks for any help!
