Description

I was testing how Rudder webapp reacted to the PostgreSQL server being unavailable.

I was running the webapp and browsing various pages, stopped the SQL server, continued browsing and got several "The server cannot be contacted at this time", restarted the SQL server, and then everything worked fine again (without restarting jetty).

However, during this period, at some point some promise generations were started. One returned an error saying "=> Exception caught during deployment process: Could not get JDBC Connection; nested exception is org.postgresql.util.PSQLException: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.". Then the next one got stuck (it's been like that for 20 minutes). The log contains this, and I don't know how to stop it:
