Hi Scott, I would suggest to go for Patch 4, which has some mid-tier fixes however in means time you can check mod_k and jvm setting for tomcat as below
To work around the issue, we had to update the workers.properties and the Apache mod_jk directives to disable retries and disable socket re-use. Apache Directives: JkOptions +DisableReuse worker.properties: worker.propertiese.retries=0 The header size periodically exceeded the max packet size supported by the AJP configuration. When the headers do not fit into a single packet, AJP drops the packet and logs an error. We resolved this by increasing the max packet size to 65536. This is more of an issue where special things are inserted into the request/response headers (SSL, SSO, other things). To address this we had to update the Tomcat AJP listener configuration (server.xml) and the worker.properties: worker.properties: worker.midtier.max_packet_size=65536 Tomcat AJP Listener (added the packetSize parameter): <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" packetSize="65536"/> Hope this will help you.
