Encompass stores frequently accessed data in a temporary, high-speed cache to keep the system fast. Cached items are grouped into tags so related entries can be found and cleared together later (for example, when the underlying data changes).
​
​

Every cached item has an expiration time. When an item expires, it is removed automatically, but the reference to it inside its tag group can be left behind.
​
​

The CleanCacheTags task scans these tag groups on a regular schedule and removes references to items that have already expired.
​
​

If a tag group ends up empty after cleanup, the task removes the group entirely.
​
​

This keeps the caching system running efficiently and prevents it from using more memory than necessary over time.

​

This task runs automatically in the background. It requires no input from you and does not change, delete, or affect any of your business data — it only manages temporary, internal system cache files.
