It is a limitation of the CrawlerSessionManagerValve. It only supports one session per client IP as it maps client IP to session ID internally. Moving the Valve to the Context (if you want it to apply to every Context you can define it in CATALINA_BASE/conf/context.xml) is a workaround. The proper fix is to change the valve so it maps context+client IP to session ID. There are several ways to do this. Please open a Bugzilla enhancement request for this and someone will take a look.
