There is nothing to be done but to fail= the request. This is intended behavior in this case. My recommendation would be for you to review all your various timeouts to m= ake sure mod_jk and Tomcat agree. Enable CPING/CPONG on the mod_jk end. See if = that improves anything. If things are still behaving oddly, please post to the users list, as Bugzi= lla is not intended to be a support forum. We can always re-open this bug if th= ere is indeed a bug (though mod_jk works in huge numbers of environments without problems, so a bug is unlikely). --=20 You are receiving this mail because: You are the assignee for the bug.= --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@tomcat.apache.org For additional commands, e-mail: dev-help@tomcat.apache.org
