Tomcat 4.1.29 - IE SocketException - [ERROR] PoolTcpEndpoint - -Endpoint ServerS

Tomcat 4.1.29 - IE SocketException - [ERROR] PoolTcpEndpoint - -Endpoint ServerS

Hi List,

  I can only trigger this exception consistently under IE 6.0
browser. When using Mozilla 1.4 problem does not occur at all. It is on
FreeBSD 4.6 and I am using JDK 1.3.1.

[WARN] PoolTcpEndpoint - -Reinitializing ServerSocket

In order to debug the issue, the default server.xml with using port 8080
and CoyteConnectors is used. I have also looked into the Tomcat 4.1.29
codes which classes have to do with stacktrace above.

As the log shows, the ServerSoket InetAddress is "addr=0.0.0.0/0.0.0.0".
Even it is reinitializing the Server Socket, it is still causing the
browser spinning, of course, another thread will be able accept.
So is something to with Native Method on the FreeBSD? Or the
ThreadWithAttributes class somehow missing its attribute? Or is it
configuration issue? I actually didn't spend too much time on Tomcat
codes. Before I dig further on this issue and perform tcpdump. I am
asking if anyone of you experience the same problem.

Any sort of information will be really helpful. Thanks in advance.

See Yam
