             Summary: DB connection and acquire lock to be retried few times before giving up
                 Key: KARAF-6037
                 URL: https://issues.apache.org/jira/browse/KARAF-6037
             Project: Karaf
          Issue Type: Bug
          Components: karaf
    Affects Versions: 4.0.4
         Environment: Apache Karaf 4.0.4

DB Lock using MySQLJDBCLock.
            Reporter: Kaja Mohideen


I’m trying to use Karaf HA/failover feature documented here : [http://karaf.apache.org/manual/latest/#_ha_failover_and_cluster]

With database lock, I see that Karaf running with the Lock as Active instance is just shutting down upon losing connection with DB.

I think, it would better if Karaf tries few times to reconnect & acquire lock before doing shutdown. When only one instance of karaf is running and DB connection fluctuates, this behavior impacts availability (needs restart from orchestration layer).

Note: I'm using start level = 1 and karaf.lock.slave.block = true
