Further update: We snooped both the web server and the middle tiers and found that the web server is sending a SYN packet which is received on the middle tier but never ACKnowledged. So far we have only seen this on posts, but we are still examining the logs. I thought the operating system is responsible for the SYN,ACK back to the web server. Or does the operating system check to see if there is any listener and the sends the SYN,ACK? Trying to figure out if we are looking at an error at the operating level or with tomcat/jasper?
