GPF During Server starup

Question

I'm getting a GPF during server startup, when the server is trying to deploy the EJB I've created. I'm running Win NT SP5 and WLS 5.1.0, SP8. Anyone have any ideas why this might be happening?
Thx in advance,
Aaron

I guess you might be initializing the map in doStartService() method. Few more options you can try based on how and when you are using this map:
1. Try lazy loading, if the map property is used in background task like scheduler where adding 15 minute to the first run is not detrimental.
Your code will look like this
public Map getMyMap()
     if( mMyMap == null )
        //Initialize your map here
        mMyMap = initializeMyMap();
     return mMyMap;
2. Try loading your map in separate thread.
    public void doStartService() throws ServiceException {
        super.doStartService();
        new Thread( new Runnable() {
            @Override
            public void run() {
                initializeMyMap(this);
        }).start();
    public Map getMyMap()
         while( mMyMap == null )
             //Pause for a sec and then try
             Thread.sleep(1000);
         return mMyMap;
This solution will work better given your map will not be used immediately after server start.
