Mapping hangs after execution

Question

Using Warehouse Builder v10gR1 (repository is 10.1.0.1.0) on a 10.1 Db
AFAIK, no changes to this mapping or objects related to mapping, but it has been hanging every execution since Saturday, whether it's run as part of a workflow or on its own. The mapping appears to be "done" -- I see it has updated the records -- and the session shows it is running this code:
DECLARE
l_env wb_rt_mapaudit.wb_rt_name_values;
FUNCTION bool_to_char (val BOOLEAN)
RETURN VARCHAR2
IS
BEGIN
IF (val IS NULL)
THEN
RETURN NULL;
ELSE
IF (val)
THEN
RETURN 'true';
ELSE
RETURN 'false';
END IF;
END IF;
END;
BEGIN
l_env (1).param_name := 'AUDIT_ID';
l_env (1).param_value := 504189;
l_env (2).param_name := 'OPERATING_MODE';
l_env (2).param_value := '2';
l_env (3).param_name := 'MAX_NO_OF_ERRORS';
l_env (3).param_value := '0';
l_env (4).param_name := 'COMMIT_FREQUENCY';
l_env (4).param_value := '1000';
l_env (5).param_name := 'AUDIT_LEVEL';
l_env (5).param_value := '2';
l_env (6).param_name := 'BULK_SIZE';
l_env (6).param_value := '1000';
:1 := upd_we_claim_lc_code_jdim_desc.main (p_env => l_env);
END;
This is the only mapping hanging like this, and I'm not sure what to look at to (a) figure out why it's doing this, and (b) make it stop. I don't have access to the workflow module (where you can apparently manually progress a step in a workflow).
Any help would be greatly appreciated.
Thanks,
Heather

Yes, it is happening consistently now -- whether running in the workflow (its normal execution) or running the mapping on its own. It normally takes maybe 5 minutes for this mapping to run, but it's hanging on the code in the original post. I suspect it is doing some clean up activity on the OWB side, since there are no sessions still trying to select from or update the target table, and for some reason it can't complete these cleanup activities for only this mapping. Anyone know what happens between the time the mapping completes its work and OWB marks the task as complete?
Thanks,
