Also happening here (feisty, 2.6.20-15-generic). It's not just TCP though, ping is also affected. Haven't tested UDP. Initial connection attempts to a given host seem to always fail with EAGAIN, and henceforth always succeed until after a certain period of inactivity, which a little experimentation showed to be exactly 900 seconds.
Here's how I measured it: a=0; while ping -q -c 1 216.239.59.104 >/dev/null; do a=`expr $a + 10`;echo $a;sleep $a;done -- First connection attempts usually fail https://bugs.launchpad.net/bugs/109764 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
