Unable to open debugger port (127.0.0.1:63777): Java.net.BindException "Address already in USE:JVM

To IntelliJ idea is love and hate Ah, love than myeclipse with more than a good hand, hate is just beginning to use is not very accustomed.

Occasionally starting debug mode with Tomcat to debug will report the following error:

Unable to open debugger port (127.0.0.1:63777): Java.net.BindException "Address already in Use:jvm_bind"

Bothered me for a long time, tried to delete the Taget folder rebuild, tried to kill the Java process and restart the machine, but it is not effective.

See this post today (https://youtrack.jetbrains.com/issue/IDEA-92953#) is just the problem I encountered, the original problem came out of the configuration of Tomcat server.

As shown, the problem is solved before the port is 63777, and then I simply deleted this tomcat server re-create, it automatically use 50424 this port, start debug mode, the problem solved successfully!

(Of course, you do not delete the Tomcat server configuration, manually modify the port number estimate is OK, but I tried it can only use the up and down arrows to change the port, good trouble.) And after the manual change is not necessarily able to use, so instead of rebuilding let IntelliJ idea automatically find good.
