      Description

      The user filters preferences are cached in a dedicated cache, but we can see that for other informations the document cache is still assessed for the following events. This can make the document cache unusable if the number of users is greater than the document cache itself (because it will constantly fill it and invalidate any other document which constantly have to be reloaded from the database).

      The workaround is to make sure the document cache is at least the number of active users plus some number estimated to be the most active documents. In general for all cache it's a good practice to use a tool like Glowroot or https://extensions.xwiki.org/xwiki/bin/view/Extension/Admin%20Tools%20Application to see which cache is full and ideally increase them when there is enough allocated RAM.
