Hi guys, Yesterday we deployed a version using precompilacion. app.yaml: ... api_version: 1
derived_file_type: - python_precompiled handlers: ... We also have a monitoring tool that makes a request to the home page every 4 minutes, and a selenium test every 15 minutes. That helps keeping the app alive, so that when users come to visit after some inactivity they don't get the 500 error. Don't know if this is bad for google but it is definitively good for our users and that is what matters to us. Since yesterday night, we haven't seen the app fail. Hope that helps to you guys :-S 2010/9/23 James Saull <[email protected]> > I have noticed that if my application is idle for a while I am likely > to get the "request was aborted..." message.
