Re: Under system account, Tomcat starts even with shutdown port conflict
You should still be consistent about how you start Tomcat in Windows. Look into reboot situations. Look into file permissions if your app writes any files. These are other places where you can get inconsistent results. I've always used Ubuntu or Solaris in production to narrow these issues. Always worked with the project distros since Tomcat e.

Found out this is working as designed. You can follow the link to where I answered my own question... https://stackoverflow.com/questions/44400047/starting- tomcat-with-local-user-causes-jvm-bind-exception/2109#2109 According to https://msdn.microsoft.com/en-us/library/windows/desktop/ ms740621(v=vs.85).aspx If both application are in the same user context then both can bind to the same port if one of the application is using the invalid address. (0.0.0.0) If both application are in different user context then we get the exception. Thank You, *Tou Vue*

The OP is running on Windows, not Linux, so there are no restrictions on port usage. Some other process is using the port. Since there are multiple ways to stop Tomcat (especially when running as a Windows service), non-availability of the shutdown port is not considered fatal. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Under system account, Tomcat starts even with shutdown port conflict
Tomcat was able to access the same port if I turned off the other service. So I don't think it's protected.

Under system account, Tomcat starts even with shutdown port conflict
Hello, I have a question regarding how Tomcat starts up under the system account and local user account in Windows. I had a Tomcat service that would start fine under the system account, but once I configured it to start under the local user account, I received a JVM_Bind exception. I looks like the Tomcat was not able to access the shutdown port configured. I figured it was a port conflict, another service was using the same port. So, I changed the port so there was no conflict, and Tomcat started up okay again. But I'm still wondering why Tomcat was able to start up with the system account even with the same port conflict. Any suggestions would be appreciated. Thank You, Tou Vue
