Symptoms
Assume that you use Always On availability groups (AG) in Microsoft SQL Server. When the AG goes offline, and if the SQL Server database is in the AG, the database Full-Text search auto crawl stops and never starts even when the AG is online again.
You may have to manually resume the auto crawl by running the following query:
"ALTER FULLTEXT INDEX ON Table_1 RESUME POPULATION"
DateTime Server The availability group 'AG' is being asked to stop the lease renewal because the availability group is going offline. This is an informational message only. No user action is required.
DateTime spid56 The state of the local availability replica in availability group 'AG' has changed from 'PRIMARY_NORMAL' to 'RESOLVING_NORMAL'. The state changed because the availability group is going offline. The replica is going offline because the associated availability group has been deleted, or the user has taken the associated availability group offline in Windows Server Failover Clustering (WSFC) management console, or the availability group is failing over to another SQL Server instance. For more information, see the SQL Server error log, Windows Server Failover Clustering (WSFC) management console, or WSFC log.

This is an informational message only. No user action is required DateTime spid61s The availability group database "ag2" is changing roles from "PRIMARY" to "RESOLVING" because the mirroring session or availability group failed over due to role synchronization.
