Describe the bug

Based on Worker logs we found that Sync status for some Postgres datasource went into "Error" state.

Explain the environment

  • Chaos Genius version: Release candidate 0.6.0
  • OS Version / Instance: Ubuntu 18.04, AWS EC2
  • Deployment type: Docker

Current behavior

  • Intermittently reproducible
  • goes into "Error" state when this happens

Expected behavior

  • Should not Error out and continue to progress eventually completing syncup and moving to "Live/completed" state

Screenshots
