SUMMARY
I was looking at my machine's journal as one does when my eye caught this message repeated several times in the same second:

Feb 15 21:57:53 ioniq kdeconnectd[2714]: kdeconnect.core: CompositeUploadJob::startListening() - Error opening a port in range 1739 - 1764

Checking the open ports, I find this:

mdione@ioniq:~$ netstat -tpln | grep kdeconn

So there must be a bug where kdeconnect somehow opens multiple ports.

STEPS TO REPRODUCE
To be hones, all I can say is that kdeconnect has been running for days if not months. I almost never close my session or reboot the machine.
