Error description

  • Error Message: N/A

.
This can only cause problems on z/OS.

Local fix

  • 



Problem summary


    

  • The JIT compiler allocates some of it's memory on z/OS via
STORAGE OBTAIN. Some of this memory was not being released via
STORAGE RELEASE upon JVM shutdown. If there are thousands of
JVMs being started and shutdown within the same address space,
then the address space can eventually run out of memory causing
an 878 ABEND.

    



Problem conclusion


    

  • The JIT compiler has been updated to release all memory
allocated with STORAGE OBTAIN upon JVM shutdown.
.
This APAR will be fixed in the following Java Releases:
   7 R1 SR3 FP10  (7.1.3.10)
   8    SR1 FP10  (8.0.1.10)
.
