Pings to hosts on that network respond with "sendto: no buffer space available". I've recompiled with MAXUSERS up at 128 and NMBCLUSTERS at 32768, both of which seem plenty high. The problem goes away, to return an hour later, after a quick 'ifconfig ep0 down; ifconfig ep0 up'. Other people seem to have run into this problem as well, but there is no sign of a fix in the archives anywhere.
