I'm getting the following error from Tomcat in the stderr log. The error looks like the typical port bind error where another process is already using that port. In the past I could use Process Monitor or netstat -aon and find what process was using it.
However, in the last month or so, I've had multiple servers for different clients get this error and no process in the list is using the port. I'm at a loss. The only way to recover is to restart the whole server (not just Tomcat). Any ideas what could cause this and how to fix it? I've tried searching, but everything I see is to address the typical problem where the port is actually in the list of active processes.
