Hi,

We use Smidge helper on several of our Umbraco 9 and 10 sites with Igloo.

After app pool recycle the CSS and/or JS are sometimes not loaded correctly (missing, or not all CSS contained).

When we recycle the app pool, they suddenly work again (no code changes).

It seems to happen randomly, we found no pattern in this behaviour.

We have this on our test and production servers and on several sites.

Does anyone have an idea what goes wrong and how to solve this? Or is this know bug?

Thanks :)

P.S. The Smidge helper is used like this:

SmidgeHelper
.CreateJsBundle("igloo-js-bundle")
.RequiresJs("/scripts/lib/ls.respimg.min.js", 
    "/scripts/lib/ls.bgset.min.js" , 
    "/scripts/lib/lazysizes.min.js",
    "/scripts/lib/fluidvids.js",
    "/scripts/lib/photoswipe.min.js",
    "/scripts/lib/photoswipe-ui-default.min.js",
    "/scripts/lib/instafeed.js",
    "/scripts/lib/flickity.pkgd.min.js",
    "/scripts/lib/forms/promise-polyfill/polyfill.min.js",
    "/scripts/lib/forms/aspnet-validation/aspnet-validation.min.js",
    "/scripts/lib/intersection-observer.js",
    "/scripts/lib/axios.min.js",
    "/scripts/ig-app.js");

SmidgeHelper
    .CreateCssBundle("igloo-css-bundle")
    .RequiresCss("~/css/lib/reset.css", 
    "~/css/ig-theme.defaults.css", 
    "~/css/lib/font-awesome.css", 
    "~/css/lib/photoswipe.css", 
    "~/css/ig-base.css", 
    "~/css/ig-header.css", 
    "~/css/ig-footer.css", 
    "~/css/ig-widgets.css"
    );
