> If you have many requests to your ejbd-service the queue from the threadPool in ServicePool.java
is filled. This queue is never processed depending on your server config. If you have only
ejbd-service enabled and the services admin, ejbds and httpejbd are disabled all is fine.
If you have two or more of these services enabled the issue could occur. The reason is the
following.
> KeepAliveServer.java has the following line to get the queue.
> final ServicePool incoming = SystemInstance.get().getComponent(ServicePool.class);
> SystemInstance.java hold components in a HahMap with the class type as key. On server-startup
the above named services are initalized in ServiceManager.manage(...). This method instances
new ServicePool for this services. Each ServicePool-instance calls in his constructor
> SystemInstance.get().setComponent(ServicePool.class, this);.
> Every other call of setComponent replace the old entry in the components HashMap. So
KeepAliveServer gets always the queue of the last initalized service.
> Workaround:
> Use only one of the four above named services
> or
> set threadsCore for your services at least as high, that the queue is never used.
