This was before we had a chat on irc. I had a chat with on irc and put together a list of the information we have so far. https://docs.google.com/a/canonical.com/document/d/1id91-eIKP_f6gJFAWmbyNtxwKxcNygOsJH2qOZqUP2c/edit I've asked webops to debug/trace into the issue if it happens again as I've been unable to find anything to act upon yet. However, I do want to note that while working on a different project we had an apache issue that was thought to possibly have been from the combo loader. At that time, we were using a tool to run the wsgi app through the Django application and we weren't sure what was up. It was on a staging server and only happened once so we didn't get much info out of the situation. Give this I'd like to get your ok to change the feature flag to enable the combo loader for all users. Overall, the combo loader has been enabled for Launchpad devs since 5/14 and for beta users since 6/12 and it appears there's the one issue that might be related to keep an eye on. -- Rick Harding Launchpad Developer https://launchpad.net/~rharding @mitechie _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : launchpad-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
