Event Handler not called

[anjan <po...@gmail.com>]

I have created an event handler to listen to the Event Topic
org.apache.sling.api.SlingConstants.TOPIC_RESOURCE_ADDED.  It is working
fine as expected.  But today I noticed that the event handler is not
called(verified through Debug) when I am adding resources.  I don't see any
exceptions in the logs.  From the Sling console, I can see that the Event is
generated successfully.  So I am not sure why the registered event handler
is not called.

After I restarted the server, the event handler is called again.  What could
be the reason for this behavior?  Any pointers.

Writing your event handlers so they always execute quickly is much
better - I usually just "take note" of what's to be done in a handler,
and do the actual work elsewhere.

Thanks Bertrand for the clue.  I guess the options could be to increase the
Timeout or configuring the event listener in "Ignore Timeouts" parameter.

your event handler might have been blacklisted, if it took too long to
process events (which stopping in debugger will also trigger IIRC) -
search "blacklist" in
http://felix.apache.org/site/apache-felix-event-admin.html for more
info.
