Hello Everyone,
I have read through this thread, and it seems that everyone is experiencing similar symptoms, but there could be several different problems here.
I would like to first point everyone to this document:
Anticipating and accommodating users—Documentation (10.3 and 10.3.1) | ArcGIS for Server
Please monitor and adjust your resources as needed. If the ArcGIS for Server is running slowly, but resources are not being strained, then there is probably an issue with the way the services are configured. Adding more instances of heavily used services to allow for more resource usage might be the solution.
If the Server (VM Guest or Physical Machine) is being strained on resources, then the System Admin/GIS Admin must discuss what the best course of action would be:
1. Add more resources to the machine (either RAM or Processing power depending on the resource constraint)
2. Set the instances of services lower
-The issue with setting the instances lower is that the ArcGIS for Server might perform slower
3. Move resource heavy programs to another machine.
- A common issue is that programs compete for resources. MSSQL is heavy RAM intensive, and so is ArcGIS for Server. In general, we would not recommend for them to be installed on the same machine. Any resource heavy program can cause an issue though. Either move ArcGIS for Server, or the other programs.
4. *This would be specific to a virtualized environment* The issue could be the Host Machine running the Guests, or the physical machine running the virtual machines, could be constrained for resources. This is a similar issue to number three, but harder to detect. Ensure that the host machine running ArcGIS for Server does not have other Virtual guests possibly hogging the other system resources.
If the server is still acting up, and you believe the resources are indeed sufficient, and you have examined the other issues mentioned above, please contact ESRI Support. There could be an issue related to our software. We are always striving to improve the way our software works, and would love the chance to review and correct the issue you are seeing, or even improve the way our program works. Just as our User Community is always finding new and unique ways to use our product, we are looking for the newest and most efficient ways build our product to handle these new workflows and technologies. Thank you all very much!!
