Error description
OA54595 introduced new function for JES to track storage areas it returns for various SSIs. After this APAR is installed - if an SSI call (such as extended status SSI80) is driven under the initiator task of the address space (before the FSS jobstep tasks are even attached); then later once the FSS jobstep is attached and running an abend378-14 can occur in IAZAKSRV. ANALYSIS: As introduced by OA54595, JES common services will track storage areas returned by JES for various SSIs. To manage/track these storage areas JES makes use of the cross memory owning TCB (ASCBXTCB). If an SSI is driven under the initiator task early in the life of an FSS asid, it will be associated with a particular ASCBXTCB. However, later when the FSS jobstep is attached and drives additional SSIs the ASCBXTCB may have changed. When JES attempts to reference/manage the original SSI storage block we no longer reference the appropriate/original ASCBXTCB and encounter abend S378 RC14 when attempting a STORAGE RELEASE KNOWN IMPACT: FSS printers impacted. Storage leak of FSVT and/or JESCB blocks VERIFICATION STEPS: 1) OA54595 installed 2) FSS address space encounters abend378-14 in IAZAKSRV 3) Early in the lifespan of FSS address space, an SSI such as SSI80 was driven under initiator task PE INFORMATION: USERS AFFECTED: All users of HBB7790, HBB77A0, and HBB77B0 with OA54595 applied: FMID PTF ---- --- HBB7790 UA96558 HBB77A0 UA96556 HBB77B0 UA96303 USER IMPACT: APAR OA54595 delivered the new function it reported but introduced a new problem (abend378-14).

Problem summary
**************************************************************** * USERS AFFECTED: * * All users of HBB7790, HBB77A0 and * * HBB77B0 with OA54595 applied. * **************************************************************** * PROBLEM DESCRIPTION: * * ABENDS378-RC14 may occur in IAZAKSRV * * in FSS address space. * **************************************************************** * RECOMMENDATION: * **************************************************************** If a subsystem interface (SSI) call, such as extended status SSI 80, occurs very early under the initiator task of an address space, subsequently, when a functional subsystem (FSS) job step runs, an ABEND378-14 may occur in the IAZAKSRV (JES address keep services) module.
Problem conclusion
TYPE/RESTART(NONE) IPL/REQUIRED(YES) CLPA(YES) CLPA is needed only if the IAZAKSRV module currently resides in the pageable link pack area (PLPA). The ABEND378-14 occurs under the indicated circumstances because IAZAKSRV specifies the wrong Task Control Block (TCB) when the module attempts to replace the Functional Subsystem Vector Table (FSVT) control block. IAZAKSRV has been modified to replace the FSVT, specifying the correct TCB, whenever changing jobstep TCBs make this necessary.
