Explanation
All of the tasks in a job step were in an SVC wait
state for the time specified in the JWT parameter in the SMFPRMxx
parmlib member.
The event control block (ECB) specified in the
wait request was never posted.  This could be the result of waiting
on the wrong ECB or not posting the correct ECB.

System programmer response
Correct any errors and execute the
job step again.  If no errors are found and the wait is expected for
that particular job step, specify TIME=NOLIMIT in the EXEC statement
to bypass all job step timing.
