Hi, I think in mod_jk 1.2.20 these old parameters changed with new parameter names, these old paramter does not take effect into your mod_jk. Please change them with new name.
Please refer URL for more details changes in new mod_jk: http://tomcat.apache.org/connectors-doc/reference/printer/workers.html worker.tomcat-publicweb-01.cachesize=10 worker.tomcat-publicweb-01.cache_timeout=600 It should be: worker.tomcat-publicweb-01.connection_pool_size=10 worker.tomcat-publicweb-01.connection_pool_timeout=600 worker.tomcat-publicweb-01.connection_pool_minsize=6 I also suggest to increase the nos for worker.tomcat-publicweb-01.connection_pool_size=50 worker.tomcat-publicweb-01.connection_pool_minsize=26 This modification you need to do in workers.properties. Please update this does not help. With regards, Babu Satasiya Cisco System Inc.
