Issue/Introduction

How can it be that XCOMJOB gets a U4094 abend with reason code X'18' after a successful execution?
 

Environment

Release: 12.0
Component: XCMVS

Resolution

This may happen if module XCOMJOB is at a fix level greater or equal than RO99935 XCOMJOB STORAGE LEAK AFTER APPLYING RO96344 (ZDEC Support) and at the same time module XCOMCINT is at a fix level lower thanRO99490 LE NOT BEING PROPERLY TERMINATED WHEN XCOMJOB CALLED AS API. The symptom is a U4094-18 abend during XCOMJOB normal termination. For example:

This abend should clear after applying fix RO99490 LE NOT BEING PROPERLY TERMINATED WHEN XCOMJOB CALLED AS API

Both fixes must be applied.
