  • Hi Himmat,

    I think this is a memory consumption issue which in turn crashes your app-pool. What can be done here is check your Google Analytics and note the lowest traffic time in a day. Once you know the lowest or zero traffic time of your site, enable a forceful recycling of your app-pool and then this issue should be resolved.

    Forceful Recycle can be enabled this way - docs.microsoft.com/.../

    Let me know if this is helpful.
