Where is the relevant code you are using?

Are you using a ServerSocket and did set the Eventprefix to ""?

I don't know exactly where crash happens, because my app run as a service and it does many tasks.

Yes, I'm using ServerSocket and seting Eventprefix to "".

So, maybe ServerSocket is the responsable by this error?

This is the Problem. It is a mistake not to set an EventPrefix for Objects which do use Events.

Set the prefix, make sure to have a Eventsub yourprefix_newconnection
