I would like mod_jk to detect when the Tomcat JVM got into an OutOfMemoryException so that mod_jk avoid to forward request to that Tomcat. If I'm not wrong, it could happen that the mod_jk balancer forward a request to a JVM in such a state, since the mod_jk isn't able to recognize as crashed a Tomcat in OutOfMemory. I would like to write a patch for the mod_jk to add such feature, but I don't know the code at all, could someone get me introduced to it? Any suggestions? Mini how-to? Support? I would appreciate them so much and I promise to try any attempt to add this feature, if I can figure out how things work in the mod_jk core and in its load_balancer. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@tomcat.apache.org For additional commands, e-mail: dev-help@tomcat.apache.org
