System crash when creating runes index on Ubuntu

[so7ow]

I experienced a repeated system crash when attempting to create a runes index with ord 0.19.0. All recent versions of ord have indexed without issue. I thought it might just be a failing disk or something (see crash details below), but now at least one other user on the Ordicord has reported a similar situation, so I thought I'd submit this issue. After each crash, I'd delete the partial REDB file and start again, and each time it would crash again. When I finally let the system repair the partial index and continue, I was able to complete the runes index. I'm happy to try to reproduce the crash and gather whatever logs would be helpful in diagnosing, if that's appropriate. Or maybe it is just a failing disk over here. 🤷🏻‍♂️

My command:

$ ord --index-runes --index index-runes-19.redb server
