I cannot reproduce this on Debian unstable with either 2.2.22-9 or 2.2.22-1.
Wild guess: Do you have a per-user process limit configured in /etc/security/limits.conf ? If no, it would be helpful if you could provide a backtrace of the process that curl connects to and hangs. There is some documentation about how to do that in /usr/share/doc/apache2.2-common/README.backtrace. But the doc is for Debian. For Ubuntu, the installing of the debugging symbols works differently (maybe someone else can provide a pointer). -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to apache2 in Ubuntu. https://bugs.launchpad.net/bugs/1028470 Title: apache2+ssl hangs on high load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1028470/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
