It was discovered that the octavia-api process, that uses the oslo.messaging package, is orphaning amqp connections with no effort to gc old connections. This leads to a large number of open files accumulating rapidly on the host filesystem and an overall negative impact on system load and resource utilization. Original report: https://storyboard.openstack.org/#!/story/2004993 How reproducible: 100% Steps to Reproduce: 1. trigger dozens of all sorts of CRUD operations 2. monitor CPU and memory usage Actual results: CPU and virtual memory usage of octavia-api container grow with the number of LB control-plane operations. Expected results: CPU and memory usage should remain mostly flat with time and operations. Additional info: This issue was also observed on Rally runs.
