Here’s another user suffering the same issue but with miniupnpd running on a debian router: 1.14.1.5488 is maxing out my MacBook Pro's CPU 24/7
Interesting to see that it’s not limited to the OpenWrt build of miniupnpd, and also affecting non-OpenWrt installs. miniupnpd is, obviously, the common factor here.
I’m really curious to know what PMS started doing differently to get so upset by this particular UPnP implementation in it’s most recent releases as it’s worked flawlessly with miniupnpd for years now.
