Subject: Re: [bug] stuck localhost TCP connections, v2.6.26-rc3+

Message-ID: <20080526142904.GA11829@elte.hu> (raw)
In-Reply-To: <20080526141713.GA5771@elte.hu>
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 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.
