hello guy, i recently disabled QOS on my router, so i got a 'boost' on my network speed. but somehow, i notice after a while of high speed torrenting (~18-20mb/s), the network interface of my mac mini will 'freeze'. there will be ABSOLUTELY no inbound or outbound transfer. all setting/monitoring apps (including system preference) related to network will freeze. only way to 're-activate' network is to restart the machine

and i checked console, i notice there are tons of error saying like "m_allocpacket_internal failed". (see attached log screenshot). and it doesn't change even if i switch network interface (from build-in ethernet to thunderbolt ethernet), and even a brand new mac mini with same software setup have the same problem


some interesting things. one is the machine will run weeks while i throttled to less then 14mb/s (using qos on router), and another is that this seem to occur pretty randomly. i mean sometimes it freezes after 10 minutes of high speed torrenting, sometimes it takes hours or even days to freeze.



anyone has any idea what's going on, or have similar experience?


btw, the applications I'm running
utorrent, os x server, plex server, hazel+automatic. that's all!


any advice and tips will be appreciated.
