Public bug reported:
For any TCP connection (http, ftp, ssh...), the first connection attempt almost
always fails, and the second and subsequent attempts almost always succeed.
The ssh error message is "Resource temporarily unavailable". In Firefox,
sometimes it will say the connection was reset, sometimes it will just fail to
download a stylesheet or image. Apt-get update looks like this:
Cannot initiate the connection to archive.ubuntu.com:80 (91.189.88.42). -
connect (11 Resource temporarily unavailable) [IP: 91.189.88.42 80]
This happens with the newest lowlatency kernels in Feisty. I can't say for
sure which build introduced it, as I skipped several kernel updates without
rebooting. It may have been introduced in a pre-release kernel. Some googling
reinforced my suspicion that it's a kernel issue, including this faq:
http://www.faqs.org/faqs/computer-security/ssh-faq/
which blames that error message in Solaris on a Solaris kernel bug. I don't
have a non-lowlatency kernel installed at the moment, but if I get time I'll
install one and report whether I have the same bug.
There are no corresponding log entries in dmesg, /var/log/messages,
/var/log/syslog etc.
