lorri Crash Report #494

Open bb010g opened 3 years ago

bb010g commented 3 years ago

Describe the bug lorri just kinda crashed on me. Twice? lorri's service did not restart until the second recorded crash.

To Reproduce Steps to reproduce the behavior:

  1. Save a watched Nix file.
  2. Unsure of what caused the first crash.
  3. Unsure of what kicked off the second crash either (the one that actually led to a restart).

Expected behavior lorri probably didn't want to crash? Also, lorri's service should have restarted after the first crash message.

Metadata Two crash reports were generated, /tmp/report-e4ca6a0e-32e3-43af-8f08-4158725d26b4.toml and then /tmp/report-70d2e818-a6b2-4092-a39f-40b0bd199930.toml.

I also am unsure of what caused it - I don't recall doing anything out of the ordinary prior to the crash 🤔
