Hi @Tevon2.0 ,
According to your screenshot, the Distributed Cache service has used all the allocated memory to store cached data. The solution is to check memory usage on the server and free more memory, add more RAM to the server, increase the Distributed Cache service memory allocation. Some specific steps and details you can check in this article. Divided into the following three steps roughly:
- First I would suggest you to check the memory usage on your system with Resource Monitor to see if any process is using a lot of memory. If the high-occupancy service process has no effect on the current server operation, the service can be disabled.
- Use this command to reconfigure the cache size of the Distributed Cache service:
Update-SPDistributedCacheSize -CacheSizeInMB CacheSize
- Restart the Distributed Cache service on all cache hosts. Central Administration>Manage services on server>Services on Server
