Since we moved to 2.5.0, we have consistently been getting this message. Can someone shed some light on this?

Hey Jason,

That looks like a client is sending a subscribe/unsubscribe/subscribed/unsubscribed presence packet with no TO attribute. Could you open the debugger window in the client that is sending the presence packet that is causing that exception in the server and post the corrupt packet? Even though we can fix the server to not generate that exception I would recommend contacting the client developers to fix the invalid presence packet that is being sent.

Regards,

– Gato

How do I figure out who is sending that packet request?

our error log was quiet for a little while after the upgrade to 2.5.1, but now the same error message is back…
