Hi,

Unfortunately the error from the logs is simply stating that the connection has been closed, though does not give us any indication as to why it's closed.

Does this only occur with this particular view?
If you can also note the time this occurred and email across the following log files (you can send them to support@yellowfin.bi) ;
-JDBC.log
-Stdout..log
-Yellowfin.log
-Catalina.out (if you have it)

Once we have these files we should be able to identify the issue.

Thanks,
David
