The default port of workbench is 8080/8081, when a conflict in port is found, . If another process is already using this port, this causes the java.net.BindException will be thrown.
Resolution
Identify the ports used, and look for other Record the port mentioned in the error entry in mci.log then identify processes that are using the same port with netstatby running netstat (on *nix systems). Example:
| Code Block |
|---|
sudo netstat -plten | grep 8080 |
( the sudo may or may not be required depending on whether your ID account can run netstat)
This will return results like
| Code Block |
|---|
tcp6 0 0 :::8080 :::* LISTEN 0 31457 1396/java |
You can find out which process is Use the output of netstat to find more details about the process using the same port by searching the running processes via ps. Example:
| Code Block |
|---|
ps -ef | grep 1396 |
