I just noticed the following exception when checking our development server. There were like 5 clients connected and it seemed to happen after one disconnected. Any ideas what might have caused this issue?

Hi @venjirai from the stacktrace it looks like it's in the underlying layers. Can you reproduce it reliably? Steps? Cheers, Joel
