Debdiff attached for precise SRU, test build here: http://people.canonical.com/~arges/lp999915/
** Patch added: "fix_lp999915_precise.debdiff" https://bugs.launchpad.net/ubuntu/+source/apt-cacher-ng/+bug/999915/+attachment/3644827/+files/fix_lp999915_precise.debdiff ** Description changed: I manage a server with apt-cacher-ng, I noted an CPU increase to 100% usage without any aparent reason, it sometimes even freezes so I have to restart the service every time this happen, but sometimes this was about twice a day... I decided to debug it to see what was happening so I follow the steps in http://www.unix-ag.uni-kl.de/~bloch/acng/html/troublefaq.html in the point 9.5, I compiled the source with DEBUG flag and run it. The next day I ended with a 2.8GB apt-cacher.err and a infinite loop of: - target: ooo vs archive.ubuntu.com, ports: 80 vs 80, good config: 0 [139752724489...@dlcon.cc:831|139753806664752] - >> dlcon::SetupJobConfig [139752724489984 | 139753806664752] - << dlcon::SetupJobConfig [139752724489984 | 139753806664752] Some time ago the desktops computers where configured using the following source line: deb http://serverip:3142/ooo hardy main /ooo was an alias to a ppa, the alias was removed from the server, and all the new desktops where configured using Acquire::http { Proxy "http://servername:3142";; }; - but some of the older machines keep the old format... + but some of the older machines keep the old format... I attach a fragment of the log where it start the infinite loop, note the time... it's an 8 seconds fragment log with 130500+ lines. I have tracked the computer that was sending the request and change the source.list, but this should be fixed in apt-cacher-ng, and handle the request a little more graceful. + + -- + + SRU Justification: + + [Impact] + * Users of apt-cacher-ng may see CPU usage of 100% due to a infinite loop in the code. + * The fix for this package is already present in quantal and beyond, and the author has provided the patch on this bug. + + [Test Case] + Use apt-cacher-ng and occasionally one may hit this infinite loop error depending on the source.list configuration. + + [Regression Potential] + * Small change, present in quantal/raring and upstream. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999915 Title: High CPU usage on broken request to apt-cacher-ng To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt-cacher-ng/+bug/999915/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
