Almost every time when I leave system to download a large file I get ral device inoperable after a while. Pinging the other peer causes these messages: > ping 192.168.0.1 PING 192.168.0.1 (192.168.0.1): 56 data bytes ping: sendto: No buffer space available ping: sendto: No buffer space available I don't believe that TCP buffer is legitimately filled up to the max because after I bring it down and back up it works fine for a long while. So why didn't this data go through before down/up? If TCP connections are slow buffers shouldn't just fill up: system can and should be preventing this letting apps to hold data streams. Something isn't quite right. Why would network device hang in a steady download scenaio? 7.2-STABLE Yuri
