You see message: DFHTM1703 applid CICS is being terminated by userid in transaction CEMT at terminal xxxx Yet the CICS regions never terminate and just hang. A dump taken at the time of the hang shows: in 1 case the CEMT task is Running on the TP TCB the other case, there are no running tasks, and the TP TCB has been detached already. In both cases CEMT's stack looks the same- being stuck in the CREATE_PTHREAD process Here are some modules from its STACK: NAME DFHSTP DFHSJJS SET_JVMSERVER SET_ALL_JVMSERVERS DFHSJJS GET_NEXT DFHSJTH INVOKE_JAVA_PROGRAM DFHDSAT CHANGE_MODE DFHDSDS4 ALLOC_OPEN PRODUCE_FREE_TCB DFHDSIT PROCESS ADD_TCB CREATE_TCB DFHKEDS DFHSJIN CREATE_PTHREAD . In the CEMT Running case, the TP tcb is in a wait out of DFHSJIN+A12, waiting for the sjki_ready_ecb to be posted.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: The JVM server create_pthread * * process hangs after the JVM has * * become unresponsive. * **************************************************************** A PERFORM SHUTDOWN command is issued to terminate the CICS region. The task performing the shutdown tries to disable a running JVM server, and needs to create a new PTHREAD. The JVM has become unresponsive, so the task will wait forever for the create_pthread to complete.
Problem conclusion
DFHSJIN has been changed to timeout if create_pthread fails to create a pthread. The CICS Transaction Server for z/OS Version 5 Release 2 Trace Entries manual (SC34-7295-00) will be updated with a new trace entry in chapter 18, JVM domain trace points: | SJ 024D | DFHSJIN | Exc | Pthread create timeout | No data |
