Gather round the campfire kids, and listen to this cautionary tale. If you are reading this blog you probably heard about Trendolizer, my trend-tracking website, powered by Movable Type. Recently I noticed the server load for it was constantly over 20, with multiple run-periodic-tasks instances running at 100% processor use all the time. Not good!

Error rebuilding file /var/www/...: Publish error in template '...': Error in tag: error in module...: Publish error in template '...': Error in tag: Error in tag: error in module ...: Publish error in template '...': Unknown tag found: ...
The weird thing was that the error only happened when publishing the particular file via the publish queue using the 'run-periodic-tasks' script, but it didn't happen when publishing the file 'by hand'.
