ArcMap users are getting the following error

"Error: The app domain with specified version id (%d) was unloaded due to memory pressure and could not be found" and the draw performance is terrible.

Our Environment:

Virtual Machine Windows 2012 R2 with 5GB memory

Standard Edition (64-bit) on Windows NT 6.3 <X64> (Build 9600: ) (Hypervisor)

Microsoft SQL Server 2014 (SP2-CU7) (KB4032541) - 12.0.5556.0 (X64)  (max memory set at 2 GB). 


Geodatabase version is 10.4.1 and matches ArcSDE version.

User is using ArcMap


Draw performance is terrible, geometry can take up to 5-10mins to draw. It started happening since last week. Previously there was no issue. Number of feature classes remain the same.

No changes were applied to the server. Users are getting the AppDomain unload error popups.

We do not publish web service from the server. 


Welcome any idea or work around to this.


Thanks in advance.
