Possible causes
- The source contains unreadable data.
- Storage or connection errors interrupted the job.
- The software cannot parse a title or playlist.
Check in this order
- Try a known-good synthetic source to separate software from hardware.
- Check free space and destination filesystem errors.
- Record the timestamp and repeated error block.
Fix steps
- Move the destination to verified local storage with sufficient free space.
- If the synthetic source passes, stop repeating the long job until the physical source or connection is checked.
When to escalate
Escalate when the same offset or playlist fails repeatedly after storage and software-path checks pass.
If it is still unresolved, collect
- drive model if physical
- software version
- source type
- sanitized error block
Known log signatures
