I ran into this crash today. If I recall correctly, I had been idling for some time, if that matters. The network itself is stable, so I don't think it's because of a flaky connection.

[7159]  INFO matterclient: reconnect successful

Let me also say that I am an extremely grateful fan of this project - matterircd is making my work life 1000% better - THANK YOU!

This is now probably fixed in master :-)
