Changing IP addresses on traffic groups in an HTTP iApp service from floating to non-floating and then performing a full sync operation, might cause mcpd to crash and write out a core file on the peer device.
The mcpd process restarts, which also results in most other system daemons restarting as well.
This occurs after changing the IP addresses on a traffic group in an iApp service from floating to non-floating, and then syncing.
Ensure that iApps and the objects within them are associated with the same traffic group.
mcpd no longer cores when syncing virtual servers in a traffic group that have non-floating IP addresses.
