Public bug reported:
Ubuntu 10.04 LTS 64-bit
Affects apt-get, wget, web-browsers
Retested on clean install of 10.04 LTS 64-bit: problem identical
Retested on clean install of 9.04 32 bit: problem not seen
Example command: wget
http://gb.archive.ubuntu.com/ubuntu/pool/main/g/gcj-4.4/libgcj10_4.4.3-1ubuntu2_amd64.deb
Result: Consistently fails after 3618204 bytes transferred (byte count is
consistent per failing URL, but varies from URL to URL).
Wireshark shows the client sending large bursts of duplicate ACKs,
preceded by a missing TCP segment (incoming). A short extract is
attached. Duplicate ACK count typically gets to 500 or more; this
happens several times during the conversation, during the "final"
occurrence, the conversation terminates unexpectedly with no FIN.
Network device: Mobile broadband. Huawei E156G.
Network Three UK. Three do not NAT their mobile data connections; there is no
router or NAT at my end, USB modem is connected directly to laptop. On the
clean-install retests (including where the problem is reproduced) there is no
firewall configured.
