Error description
DeadLock detected in NodeAgent process during shutdown: Deadlock detected !!! --------------------- Thread "Non-deferrable Alarm : 2" (0x000000003187D400) is waiting for: sys_mon_t:0x000001002DCEF0E8 infl_mon_t: 0x000001002DCEF130: com/ibm/son/mesh/Peer@0x00000000823C1D00 which is owned by: Thread "sonOutThreadPool : 14" (0x0000000031947100) which is waiting for: sys_mon_t:0x000001002D660138 infl_mon_t: 0x000001002D660180: com/ibm/ws/bbson/BBFactoryImpl$MainMutex@0x00000000823E2F40 which is owned by: Thread "Non-deferrable Alarm : 2" (0x000000003187D400) We can see that the thread "Non-deferrable Alarm : 2" owned lock com/ibm/ws/bbson/BBFactoryImpl$MainMutex@0x00000000823E2F40 and waiting for lock com/ibm/son/mesh/Peer@0x00000000823C1D00 which is owned by "sonOutThreadPool : 14". At same time, "sonOutThreadPool : 14" is also waiting for the lock owned by "Non-deferrable Alarm : 2". Both of the two threads didn't release the lock and are waiting for the other lock.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Network Deployment edition * **************************************************************** * PROBLEM DESCRIPTION: Deployment Manager or Node Agent * * processes are observed to hang during * * normal shutdown. * **************************************************************** * RECOMMENDATION: * **************************************************************** The shutdown sequence of Deployment Manager or Node Agent processes hang due to a deadlock between mutex objects com/ibm/ws/bbson/BBFactoryImpl$MainMutex and com/ibm/son/mesh/Peer. The deadlock is due to a timing window during shutdown when components are closing out their BBSON bulletin board subscriptions as the bulletin boards themselves are being closed.
Problem conclusion
This deadlock issue was addressed by adding yet another mutex, com.ibm.ws.bbson.SubjectSubscriptionImpl.SUB_CLOSE_LOCK, which must be obtained prior initiating closure of either a subject subscription or an entire bulletin board. The fix for this APAR is currently targeted for inclusion in fix packs 8.5.5.12 and 9.0.0.4.
