Agree. Don't rely on OS to save you from fail over. Even AIX HACMP is NOT a
great solution, working on this I have seen a lot of horror even in fail
over test. I know of financial institution which loss $17 million in 3
hours of failover failure and eventually migrated to Tandem mainframe

it on the database or memcached servers, e.g. PHP's
session_set_save_handler().

Are the apps all java on the jboss? Httpd can load balance between the
