Hello all. Let me start with a newbie alert. I am a system administrator responsible for two systems running JBoss 4.0.2 on Solaris 9. We have had the system up for a few weeks with the developers working on their code. Today, the networking group put a Cisco CSS load balancing appliance.
All of the sudden, we are getting the following errors:
14:56:37,075 ERROR [PoolTcpEndpoint] Socket error caused by remote host /10.99.72.100
java.net.SocketException: Invalid argument
at java.net.PlainSocketImpl.socketSetOption(Native Method)
Hello! Answering my own question here. Our networking group fixed this by making the CSS's send http keep alive packets instead of generic TCP keep alive packets.
In hindsight, this was probably not a problem at all. It just generated a lot of error messages on the JBoss side.
