Comment 21 for bug 89160

My problem was solved when I

edited /etc/sysctl.conf

and added the following two lines

net.ipv4.tcp_wmem = 4096 16384 131072
net.ipv4.tcp_rmem = 4096 87380 174760

This seems a little geeky, and I would hope that the Ubuntu developers
somehow address this issue in future releases. (It wasn't a problem in
7.04; appeared in 7.10 and continued in the 8.04 (beta).)
