While updating firewall rules such as adding/deleting a blacklist, mcpd memory grows by a small amount with each update.


mcpd memory grows unbounded; over a significant amount of time with many changes and no restarts, mcpd can run out of memory and oom killer can trigger a failover.


This can occur when making changes to firewall policies.
