Tested on 5.1.X version of mysql and not able to reproduce it. Kiran which version of mysql
have you tried?

> 1)I have created a DB replication with two masters M1 and M2  
> 2)Have enabled the parameter db.ha.enabled=true and then made CS setup is up with the
db replication.
> 3)Made the M1 down initially and the M2 down.
> 4) CS tries to reconnect to the databases and never goes down.
> 5)Tried with the  db.ha.enabled=false and then made the M1 down.
> 6)The CS goes to shutdown immediately.
> Expected result is:
> CS should retry for the DB's to come up for some fixed time(say 10 mins) and then should
go down. May be we need to add a parameter defining the number of retries or number of secs
to wait for either of Db's to come up.
