MCPD restart
- Provision LTM and configure 4096 extraMb - Load 16k nodes config - Observe 16000 nodes, one pool with all nodes associated, and one VS - And then load VS config using load sys config file, and the incoming VS should have the same pool name as the existing one
- While loading a new VS config with pool, make sure not to use the same pool name as the older one - First, load the system configuration to the default settings, and then load the new VS file
As it is taking more time, while handling large VS status updates, heartbeat is sent to SOD from MCPD to make sure, it is intact and SOD will not kill MCPD
