It was fixed by hanging up the dialup connection and reconnecting. Also running squid, apache, icecast, postgresql. However I don't think it ran out of mbufs: 137/640/16384 mbufs in use (current/peak/max): 132 mbufs allocated to data 5 mbufs allocated to packet headers 131/390/4096 mbuf clusters in use (current/peak/max) 940 Kbytes allocated to network (7% of mb_map in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines Also have large send and recieve buffers set in /etc/sysctl.conf: net.inet.tcp.sendspace=65535 net.inet.tcp.recvspace=65535 It also happened about a month ago but I decided to let it slide unless it repeated.
