Thank you both for your advice. I'm pushing towards upgrading the Apache+mod_jk stack as well. Our last tests with the latest Tomcat and mod_jk still showed a lot of CPU time being spent in sendbb methods, with some threads being stuck in that method for long time. We actually found out a lot of "unrecoverable error 200, request failed" error messages in the mod_jk log (roughly around 1k per hour), so I'm starting to wonder if there's any issue with the firewalls and the network infrastructure. What would you think about that? [Thu Dec 03 16:58:52 2009][31539:42688] [info] service::jk_lb_worker.c (873): unrecoverable error 200, request failed.
