Completed LOAD phase in db2diag.log, db2 load never completes

[tftobin]

Hi,
In the db2diag.log logs on several systems, I see
Completed LOAD phase at 05/21/2012 14:48:10.785788.
The db2 utility which is loading a script never completes.
db2 list applications show detail
shows UOW Waiting. These scripts end with a commit;
and have succeeded in the past. The commit is not being executed. Does anyone have any idea why?
script:

load from
/data1/lineitem.tbl.15
of del modified by coldel|
insert into DB2INST1.lineitem nonrecoverable;
commit;

log:
-bash-3.2$ cat load_db2_database_lineitem_15.log
load from /data1/lineitem.tbl.15 of del modified by coldel| insert into DB2INST1.lineitem nonrecoverable
-bash-3.2$


db2 list applications global

DB2INST1 db2bp 59 *N0.db2inst1.120521175831 TPCH1TB 3

Thanks!
