Hi All,

 

We have PostgreSQL master-slave replication configuration with 4 servers. 

After shutting down one standby server, we found below errors on all other 3 servers and the applications couldn’t access the database due to the timeout.

DAO-00002 datasource connection failure:Time out waiting for a DefaultDataSource

ERROR SQLException code: 0 SQLState: null

 

What could be the cause of the errors?  Would anyting be helpful to prevent it from happening?

 

Thank you for the help!

 

Cheers,

Joanna Xu
