    1. User unable to force off Event monitor application  (might
    have some locks on user tables which cause contention)
    2. Coordinator agent is on Pending RemoteRequest state.
    
    Stack of Coordinator agent might show the following:
    
     sqloWaitEDUWaitPost
     sqkfChannel::WaitRecvReady
     sqkfChannel::ReceiveBuffer
     sqkdBdsBufferTable::dequeueBuffer
     sqkdBdsBufferTable::getNextBuffer
     address: 0x00002AAAACAC07D2 ; dladdress:
     address: 0x00002AAAACAC05E9 ; dladdress:
     address: 0x00002AAAACAC0B84 ; dladdress:
     sqlkdReceiveReply
     sqleReceiveAndMergeReplies
     sqlkdInterrupt
     sqleDssStopUsing
     sqeApplication::ForwardStopRequest
     sqeApplication::AppStopUsing

     address: 0x00002AAAABB73982 ; dladdress:
     sqleIndCoordProcessRequest
    
    
    3. Active subagents on other partitions will show the following
    stack:
    
      sqloWaitEDUWaitPost
      sqmEvmonWaiter::waitForEvmon
      sqm_evmon_mgr::start_evmon
      sqlm_bds_start_monitor_hdl
      sqleSubRequestRouter
      sqleProcessSubRequest
      sqeAgent::RunEDU
      sqzEDUObj::EDUDriver
      sqlzRunEDU
      sqloEDUEntry
    
    4. db2diag.log will have entries like the following:
    
    FUNCTION: DB2 UDB, base sys utilities,
    sqeAgentServices::RequestAgentForAppl, probe:6
    MESSAGE : Error processing app entry... SQLCODE =
    DATA #1 : Hexdump, 4 bytes
    0x00002AAAC2FF2248 : 48FC FFFF

    and
    
    FUNCTION: DB2 UDB, database monitor, sqmEvmonWriter::startMeUp,
    probe:71
    MESSAGE : ZRC=0x800D0003=-2146631677=SQLM_ACT_INTRP
              "Event monitor activation interrupted"
