In certain cases, the mcpd service can crash during configuration synchronization. An object was getting deleted while still being processed.
A BIG-IP system that was active will go to standby when MCPD crashes.
This can occur after an upgrade.
Sometimes initiating the sync from a local (e.g. root or admin) user can work around this issue, but this has not been shown to be true in every case.
During a config sync, steps were taken to ensure that mcpd objects are not deleted until after they have been fully processed.
