Standby Has Fewer Online VIPs Than Active – Requires Manual Monitor Reset

Sounds like a possible issue with stale monitor states or a sync problem between the units. Have you tried forcing a full config sync and clearing the monitor stats? Also, check if there's any persistence in the monitoring cache causing this. If removing/re-adding the monitor fixes it, maybe something’s getting stuck in the process. For the TCP monitor failures, could be network latency, firewall interference, or just strict timeout settings. Might be worth tweaking those if possible.
