I run a java application (server-side, third party product) on Solaris (SunOS fixdev 5.6 Generic_105181-19 sun4u sparc SUNW,Ultra-1). The applications listens on a specified port. I observe that even after killing the application, the port remains blocked for ever. The port gets freed in around 5 min if I run the same application SunOS etsdev0 5.6 Generic_105181-21 sun4u sparc SUNW,Ultra-80. The ports are freed instantaneosly on NT.

If I do netstat, I get the following:
I also noted that the last line of netstat (SYN_SENT) appears intermittently.

Well, unfortunately I don't know how to anwer your question offhand. If you don't get an answer from someone else here, I recommend asking on the "Sockets and Internet Protocols" topic. I see that you've been away from these forums for a while - you should also know that we have instituted a policy on usernames, which can be found here. You need to register a new account name with a first and last name. Thanks.
 
Don't get me started about those stupid light bulbs.
