I have a JAVA application that crashes and leaves a TCP port open. When i issue the command netstat -a -n -o i see the port is still in listening status. It shows a PID as well. Then i look at task manager and the PID doesn't exist. I also tried command taskkill /PID and the PID was not found. How can i close the open TCP port? Thanks, JimJim

1. Unless you specify your server operating system, this question is considered off topic. 2. Use Process Explorer instead of Task Manager. It would be better tool than Task Manager. http://technet.microsoft.com/en-us/sysinternals/bb896653 ...or you can follow the procedure by Process Monitor http://technet.microsoft.com/en-us/sysinternals/bb896653 3. Look into firewall to find which function persists and let the port opened. 4. More information on the Java you will find here https://forums.oracle.com/
