Please respond to Re: Intermitant DB Problem in
"Tomcat Users tomcat:java.sql.SQLException: Io
List" exception: Connection reset by
<[EMAIL PROTECTED] peer: JVM_recv in socket input
che.org> stream read
Two questions:
1. Is the db server on the same box as the tomcat server? If not, have
you ruled out network hardware issues between the db server and tomcat?
2. Does your db pool definition have the attribute
validationQuery="select 1"? That would pre-test your connections before
returning one on ds.getConnection(), regenerating them if they fail.
