Hi, Currently we were trying with new mod_jk 1.2.21 version and we got same error message but we do not have problem due to it retries and reopen new socket and continue serving jsp pages. We are using Apache 2.0.53, mod_jk 1.2.21, Tomcat 5.0.28 and RHEL3 update5. Our architecture is HW load balancer - two Apache + mod_jk server - thirteen tomcat servers load balanced.
Workers.properties for one of tomcat: worker.tc_3_4.host=cna-stg-app-16 worker.tc_3_4.port=8003 worker.tc_3_4.type=ajp13 worker.tc_3_4.lbfactor=1 worker.tc_3_4.connection_pool_size=50 worker.tc_3_4.connection_pool_timeout=0 worker.tc_3_4.socket_timeout=0 worker.tc_3_4.socket_keepalive=1 worker.tc_3_4.recovery_options=0 worker.tc_3_4.sticky_session=1 We change pool_timeout and socket_time to 0 as above but it did not help it still gives same error. We also tried connection_pool_minsize=40 but that also did not help.
