So log collector enters infinite loop, consuming 100% CPU. Version-Release number of selected component (if applicable): IS19 How reproducible: 100% Steps to Reproduce: 1. install rhevm + dwh + reports 2. run log collector utility 3. Actual results: Tool enters infinite loop Expected results: logs collection Additional info:
