Severity: 4-Minor


When a full config sync is done to a device group with large number of partitions: -- The config sync operation takes a long time to complete. -- There is a spike in CPU usage on the device where config push is initiated. -- The mcpd daemon is unresponsive to other daemons, such tmsh, GUI etc., as it is busy pushing the config sync. -- iQuery connections are terminated due to high CPU utilization.


The operation takes a long time to complete, minutes on a BIG-IP Virtual Edition (VE) configurations, and varies by platform and the size of the configuration. For example, config sync on a medium BIG-IP VE setup running v15.1.0.1 with 512 partitions takes ~3 minutes. Impedes management of device as well as terminates iQuery connections to GTM/DNS devices.
