After dynamically upgrading to TLMS R140 on our test system, we are encountering tape job issues. One tape job produced a dump with ABEND=S0C4, other tape jobs just sit waiting for a tape mount.
JOB22493 IEA794I SVC DUMP HAS CAPTURED: 833
DUMPID=004 REQUESTED BY JOB (AAAABBBB)
After a dynamic upgrade from TLMS r12.6 to r14.0, a S0C4 abend
may occur during WTO SSI processing of a tape mount message.
This is because of storage being referenced with the new
increased length of the CA TLMS Mount_List_Element_Table
v/s the length of the r12.6 Mount_List_Element_Table
Also during a Dynamic upgrade from TLMS 12.6 to TLMS 14.0,
it is possible that a X'18' byte overlay could occur if the
last entry in the TLMS Mount_List_Element_Table is cleared with
the length defined in R14.0.
