[tor-onions] [warn] connection_edge_process_relay_cell (at origin) failed

Hi!

I have a hidden service on Tor 0.2.9.10 and a log file filled with:

[warn] connection_edge_process_relay_cell (at origin) failed.

The warnings appear about a minute after starting up and every 30 seconds afterwards. Service eventually degrades to only accepting a fraction of connections.

I can only get the service completely online again with a restart.

To improve uptimes I have the restart running automatically every 20 minutes. I hope there is a more elegant solution to the problem.

Maybe worth saying that this only became an issue when the service started experiencing much higher traffic volume. Despite high volume the box is idling, the tor process is at about 5% CPU and there is lots of available memory.
