Port hang issue in AIX Version 5.3
Thanks zaxxon for the reply.

Will keep in mind regarding the the format while posting a thread.

--------------------------------------

1. 'AIX and WebSphere up-to-date' by any chance is this concerned with the JDK version?

2. Found the following errors in the application logs while the port is in hanged status:-

Code:
 
Exception in Constructor 
sendData:my Data Length is:194
sendData:sending length of:194
 length of the string 194
Exception in sendData64
java.net.ConnectException: Connection timed out: connect
 at java.net.PlainSocketImpl.socketConnect(Native Method)
 at java.net.PlainSocketImpl.doConnect(Unknown Source)
 at java.net.PlainSocketImpl.connectToAddress(Unknown Source)

 at java.net.Socket.connect(Unknown Source)
 at java.net.Socket.connect(Unknown Source)
 at java.net.Socket.<init>(Unknown Source)
 at java.net.Socket.<init>(Unknown Source)

At this point of time when we are trying to connect to the same port it is throwing an error ' Not able to connect to the port'.

3. Nope, we are not able to create any further connection after the port gets hanged. The output of netstat -an | grep <port no.> shows all the connections in ESTABLISHED status.
