there's TCP ACK activity every 120 seconds:
16:19:05.260000 IP europe.37198 > europe.distcc: . ack 2022529163 win 257 <nop,nop,timestamp 233526 221526> 16:19:05.260000 IP europe.distcc > europe.37198: . ack 1 win 0 <nop,nop,timestamp 233526 7020> 16:21:05.260000 IP europe.37198 > europe.distcc: . ack 1 win 257 <nop,nop,timestamp 245526 233526> 16:21:05.260000 IP europe.distcc > europe.37198: . ack 1 win 0 <nop,nop,timestamp 245526 7020> 16:23:05.260000 IP europe.37198 > europe.distcc: . ack 1 win 257 <nop,nop,timestamp 257526 245526> 16:23:05.260000 IP europe.distcc > europe.37198: . ack 1 win 0 <nop,nop,timestamp 257526 7020> 16:25:05.260000 IP europe.37198 > europe.distcc: . ack 1 win 257 <nop,nop,timestamp 269526 257526> 16:25:05.260000 IP europe.distcc > europe.37198: . ack 1 win 0 <nop,nop,timestamp 269526 7020> 16:27:05.260000 IP europe.37198 > europe.distcc: . ack 1 win 257 <nop,nop,timestamp 281526 269526> 16:27:05.260000 IP europe.distcc > europe.37198: . ack 1 win 0 <nop,nop,timestamp 281526 7020>
The socket on the other side of the localhost connection, 10.0.1.15:3632, produces no packets.
a detail i forgot to mention: i reproduced the same TCP hang on a 32-bit system and on a 64-bit system as well.
