Extreme database and file system bloat

  • Hi there, I’ve generally loved this plugin but need to report a serious recent issue on one site, hosted on WPEngine. For some reason the plugin went nuts, and every 7 days would dump a huge amount of data to the database and cache/fvm/min folder. The database alone, which I just cleaned out, had 7.5 GB of stuff in it for FVM’s two tables. I’m in the process of deleting the cache folder.

    I plan to try reinstalling the plugin again afterwards and I’ll reply here if it keeps happening, since maybe it was a one-off weird issue. But I wanted to let you know about it.

    Hi, it’s not too weird at all, (if you understand what it’s doing) but it’s undesirable, of course.
    Please check if you have some dynamic css or js file that is being minified (like the name or query string changing on every uncached pageview). That should be the only time where that kind of thing can happen.

    If you minify a dynamic file with a unique name or query string (some developers add a query string that is time based to avoid caching), whenever the page is requested, the name will change, leading to a new file being found and thus minified again.

    If you cleared the cache and then google comes and craws your site anew, it’s going to find as many different dynamic file names as the amount of pages it crawled. So if google spidered your site and fetched like 10k pages, it will see 10k alternative names for the same dynamic file, which FVM also sees… so it minifies it again and again (because the name is different every time).

    To avoid that, you need to exclude the file, either by some partial path or some unique part of it’s name, and it will leave it alone. Else, if it’s common code, change your code so that it enqueues with a fixed query string value, so it’s always the same url across all requests.
