Nov 24 17:09:28-044723 core-21778 ERROR Assertion failed at gnunet-service-core_clients.c:617. Nov 24 17:09:28-054024 core-21887 ERROR Assertion failed at gnunet-service-core_clients.c:617. |

AFAIU, nse tries to send a message to a peer that core thinks that nse does not know. |
|
|
After re-running with 0001960 fixed, this doesn't happen anymore... |
|
|
The crashing assertion is still a real bug, it should be replaced with dropping the request. The ultimate cause of why you could reproduce this before and no more now (NSE crashing) doesn't matter -- core must never crash just because a client connects/disconnects. |
