Running 0.4.1 Alpha (ubuntu v3 build). Stopped farmer for some maintenance - reported graceful shutdown. Attempts to restart farmer a few minutes later all fail with error:

User mentioned that if they wipe summary they are able to start without error, while this is a temporary fix, the user shouldn’t be expected to wipe summary on every reboot.

This error was reported by @jrwashburn and has also been observed by @jim-counter.

I’m trying to reproduce the error on my side.
Is it possible to share the malformed summary file, and it’s full path?

I think it may be related to null characters, I need to investigate more

I have not been able to reproduce - sorry. I will try a few recycles on 0.4.2 alpha as well…
