Scheduled backup reports "error: can't start new thread"
Open, Needs TriagePublic

Description

Steps to reproduce:

  • Configure Backups (aka Deja Dup Backup Tool)
  • Wait for scheduled backup to run

What should happen:

  • Notification that backup is complete
  • Restoring the backup succeeds

What happens instead:

  • Notification that an error occurred
  • Error window pops up (message below)
  • Restoring the backup succeeds (despite the error)

Notes:

  • This issue is intermittent (more frequent failures than successes)
  • The error message also pops up after scheduled restore test
  • The error message does not appear after invoking a backup manually

Error message:
