Are Linux or Windows user ? My 1st advice was for Linux system, but if you are using Windows, you can try typing in shell(cmd.exe)
netstat -ab
You will see all opened ports and the processes associated with them. Then you should know what to kill using Task Manager.
Also check your firewall settings(maybe fw is blocking pol.exe from opening ports or blocks ports higher than 1023) - you can even try to disable it for a while and check the difference.

can the pol block it's self?
I am using pol for a few years and it happened one or two times, so it shouldn't. Except bad aux service configuration or listening ports, that is always your system issue.
