Current Behavior
I’m having an issue where random episodes do not clean up. In the logs I get the following. The thing is that the file processes just fine and is playable in plex without issue. It seems like sonarr is checking for the file size before the copy is complete or something. There are no logs in sabnzbd of any issues. I’m getting this on both sonarr instances as well as my two radarr instances.
Expected Behavior
Expecting consistent cleanup of sabnzbd.
Steps To Reproduce
Unable to reproduce. It happens unpredictably.
Environment
- OS: Ubuntu on Proxmox - Sonarr: 4.0.15.2941 - Docker Install: Yes - Using Reverse Proxy: Traefik - Browser: Edge - Database: Postgresql 14.18
