Hi @Tevon ,

The Distributed Cache (DC) uses 10% of the total physical memory on the server: the Distributed Cache service uses half of that memory allocation for data storage (also known as cache size) and the other half of that memory allocation is used for memory management overhead; when the cached data grows, the Distributed Cache service uses the entire 10 percent of the allocated memory.

Resolution: Check memory usage on the server and free more memory, add more RAM to the server, increase the Distributed Cache service memory allocation. Here are steps:

1.First of all check the existing memory allocation for the Distributed Cache service on a server by executing the following cmdlets at an administrative PowerShell:

Use-CacheCluster 
Get-AFCacheHostConfiguration -ComputerName ComputerName -CachePort "22233"

2.To reconfigure the cache size of the Distributed Cache service.

Update-SPDistributedCacheSize -CacheSizeInMB CacheSize

3.Restart the Distributed Cache service on all cache hosts. For more detail information, please refer to: The current server is running low on memory

Avoid this in the future: I suggest you to use Resource Monitor to check the memory usage in your system and understand if there are processes who are using a huge amount of memory. If you find that a process is taking up too much memory and you don't need to use it, you can disable the service.

Note: If your cache hosts are part of a cache cluster, do not start or stop the Distributed Cache service as described here. Instead, see Add or remove a server in a Distributed Cache cluster later in this article.

To start and stop the Distributed Cache service by using Central Administration

In Central Administration, click Application Management.

In Service Applications, click Manage Services on Server.

On the Services on Server page, locate the Distributed Cache service.

If the Distributed Cache service is started and you want to stop the service, under Action, click Stop. If the Distributed Cache service is stopped and you want to start the service, under Action, click Start.

To start the Distributed Cache service by using SharePoint Management Shell

At the SharePoint Management Shell command prompt, run the following command:

$instanceName ="SPDistributedCacheService Name=SPCache" $serviceInstance = Get-SPServiceInstance | ? {($_.service.tostring()) -eq $instanceName -and ($_.server.name) -eq $env:computername} $serviceInstance.Provision()
