Hi there,

I am attempting to run Calibre's content server (version 1.38) on port 8080 default on a Mac OS X 10.9.3 machine. I am getting an error: IOError("Port 8080 not free on '0.0.0.0'",)

At first I thought that another application was actually using that port. However, after checking with netstat -a and lsof -i, I have not seen any process using port 8080. There is no reason that port 8080 should not work.

On the other hand, when I set Calibre to use port 8081, the content server works. As such, that would lend me to believe that port 8080 is actually in use.

Does anyone have any suggestions on how to troubleshoot this further?

Thanks!

Best Regards,
Eric
