I'm troubleshooting an odd issue on my Drupal 7 site where it seems that old versions of our aggregated CSS & JS files are used some amount of time after a cache clear. How this is playing out is that I'll make some update to our CSS or JS, then clear the cache via
drush cc all (I've also used the UI to manually clear the cache). I get an updated version of the CSS / JS for a while. At some point (typically I've noticed it a few hours later), the page serves the old version of the aggregated file.
I've pulled mysqldumps of the site, and can see that the values in the
variable table for
drupal_css_cache_files, for example, contain a reference to the old aggregate rather than the new.
I found this issue on drupal.org (and I'm not sure it's exactly the same thing), but one of the suggestions involves deleting all files in
<root>/cache, which I don't have. Would this be the same as deleting the files in
Another part of this that may or may not be related is that I see in my site logs "page not found" requests for old aggregated files that don't exist anymore.
I'm hitting a wall in troubleshooting, since it seems like the actual database value for the new aggregated file is being reverted. Anyone know what might be going on here?
