Hey everyone,

I know that this issue popped up in the past but i couldn't find the solution though i tried what users suggested.
I'm running Pentaho's community version on ubuntu 12.04 64bit, when i start the BI console everything is fine, when i stop and start it again i get the following error on the website:

type Status report
description The requested resource () is not available.

Apache Tomcat/6.0.29

The Pentaho logs gives this error:
2013-08-02 10:32:53,655 ERROR [org.hibernate.util.JDBCExceptionReporter] socket creation error
2013-08-02 10:32:53,945 ERROR [org.hibernate.util.JDBCExceptionReporter] socket creation error
2013-08-02 10:32:53,946 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] could not get database metadata

And the catalina log:
SEVERE: Error listenerStart
Aug 2, 2013 10:32:54 AM org.apache.catalina.core.StandardContext start
SEVERE: Context [/pentaho] startup failed due to previous errors

What exactly should i change in the connection properties?
What did i miss while setting up the enviroment?

If i restart ubuntu everything works fine again, i know this topic popped up few times but after trying all suggested solutions i don;'t know what to do anymore :\

Thanks for helpers,
