Investigate frequent TestPool test timeout

    • Type: Icon: Task Task
    • Resolution: Fixed
    • Priority: Icon: Major - P3 Major - P3
    • 1.4.7
    • Affects Version/s: None
    • Component/s: Testing
    • None

      It appears to be a deadlock. This may likely be a test-only issue.

      Example task failure

      This is the relevant log output:
