Memory Usage High on Controller due to large number of IP address groups

Products

• VMware Avi Load Balancer

Issue/Introduction

Multiple events are noticed on the controller related to controller_service_failure and controller_process_stopped. 

Cause

The events controller_service_failure or controller_process_stopped are suggestive of high memory usage on the controller.  As a result, the memory balancer feature kicks in and restarts a few processes (based on priority) to bring the System memory utilisation to optimum. 

The high memory is consumed by  avi-logmgr process which is due to the presence of a large number of IP address groups.  

 

Resolution

As a workaround, the overall system memory can be increased and then increase the allowed memory usage by avi-logmgr.

It is recommended  to contact Avi support team to help with increasing the allowed memory.
