Error description

  • When trying to stop an application server from the
    administrative console, the AppServer fails to stop with error:
    "Servername is not running". After enabling traces with
    trace string *=info:Admin=all:com.ibm.ws.management.*=all,
    you see this in the trace:
    
    
    
    [6/25/08 10:10:25:068 CEST] 00000074 PidWaiter     <
    ContactThread.run
    contact / returntrue  true Exit
    [6/25/08 10:10:25:068 CEST] 0000006c PidWaiter     3    Expected
    Exception Recieved
                                     java.lang.InterruptedException:
    operation interrupted
     at java.lang.Thread.sleep(Native Method)

    com.ibm.ws.management.nodeagent.PidWaiter.contact(PidWaiter.java
    :1069)

    com.ibm.ws.management.nodeagent.PidWaiter.run(PidWaiter.java:392
    )

    [6/25/08 10:10:25:068 CEST] 0000006c PidWaiter     3   Sleep
    Interval
    300000
    
    All the above 3 steps happened during same timestamp. So somehow
    Pidwaiter code goes to sleep method though the PidWaiter
    contact() thread returns true on that time itself.
    
    Then pidwaiter needlessly sleeps for 5 mins during this case.

    ****************************************************************
    Delay in returning pidwaiter contact() thread.
    
    In the following nodeagent's PidWaiter trace, the 5 minute
    sleep is not required. Contact() method returns at the
    exact timestamp where Thread.sleep() starts.
    
    [6/25/08 10:10:25:068 CEST] 00000074 PidWaiter     <

Problem conclusion

  • Source code has been modified to a add wait statement before
    Thread.sleep().
    
    The fix for this APAR is currently targeted for inclusion in
