Symptoms

A particular stage of validation can take longer than the ha-daemon heartbeat interval, and while nothing is actually wrong, the system responds as if there is an unresponsive daemon, so the system restarts it.

Impact

MCPd restarts.

Conditions

iRules must be present in the configuration that the system is loading.

Workaround

On the BIG-IP system, run the command: tmsh mod sys daemon-ha mcpd heartbeat disabled.

Fix Information

Added additional heartbeats during validation, so HA daemon_heartbeat mcpd no longer fails on load sys config.
