Okay, that's what I figured, so I think we're all on the same page. Thanks much. I guess the only way to be 100% certain is to try it, watch it carefully, and be ready to reconfigure and restart all the tomcats if it looks like things are going to get dicey (like if I see iowait and/or swap usage start to climb). Thankfully, because of the way we do load balancing, this can be accomplished gracefully without severely impacting customers. --Eric Disclaimer - February 8, 2011 This email and any files transmitted with it are confidential and intended solely for Tomcat Users List.
