- Original Message (edited) Subject: Two Tomcat 7.0.11 installations in the same Linux instance, running both on port 80, without conflicts? I'm considering a parallel Tomcat installation in the same Linux VPS, both running at the same time. I perfectly know that it can be done, but how do I do with the port conflict? Use different IP addresses for each Tomcat; specify the IP address chosen via the Connector address attribute. - Chuck - Original Message (edited) Don't forget to either add an address attribute in the Server element (or change the port) for the shutdown command. BTW, nice new attribute (address) for the Server element. . . . just my two cents. /mde/ - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Thanks, I will read that.

Hi Chris, I'm improving my apps frecuently, so everytime I do it I need to upload a new WAR file. When that happens, I face the leaking problem that so far I haven't solved. For that reason, I'm restarting Tomcat. My new app should not be hosted in the same Tomcat instance for that reason. I will definitely think about redundancy soon, as soon as my new idea shows some profit and I'm able to spend some more, thanks for mentioning that!
