@bernhardschmidt yes, it's the same. Any easy way to reproduce this issue?

Unfortunately not, this happened after roughly 20 hours of operation as a full eduVPN node here (see #13 for the setup)

The receiving path for TCP connections has been totally reworked (and simplified), therefore this bug is "kinda" invalid at the moment.

Would anybody be able to check if this issue still exists and post the new stacktrace? It'd be greatly appreciated.
