You may have encountered a bug that I've reported 4 years ago. I'm not sure if it has been fixed as we've only tested Piranha for a few days and have never used it since. Check the access and/or error logs of your tomcats to see how the requests are corrupted. https://bugzilla.redhat.com/show_bug.cgi?id=199243 regards, rainer _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - [email protected] Send requests to [email protected] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
