Summary

I noticed that every night when my logs get rotated, a non-fatal assertion appears at the beginning the log. I can manually trigger this issue but reloading Tor by hand (sudo systemctl reload tor).

What is the current bug behavior?

This bug message just appears, but I could not find any impact yet.

What is the expected behavior?

This message shouldn't appear, right?

Environment

• Tor version 0.4.5.6 (0.4.5.6-1~d10.buster+1)
• Debian 10
• Installed using apt (via the official Tor repository)
• This Tor instance is a bridge relay
• This Tor instance exposes a v3 HS (Bitcoin Core 0.21.0)
