Now I'm not so sure. > Dick, Are you sure the Tomcat process is actually shut down? Just the brief look at the stack trace, it's looking like the JVM process didn't get killed and there's cruft on the local thread. You might also consider using the new net.liftweb.mapper.StandardDBVendor rather than the roll-your-own DB vendor in Boot. I'll add a ticket to make sure that StandardDBVendor registers with the container shutdown so it correctly closes all connections.
