Dynamics Nav 2017 instance suddenly using more than 80% CPU...

Jordi_Llompart

Hello!!!

I've got a very big problem with a Dynamics Nav 2017 instance. This instance is only used to call ODATA web services, it provides information to our .NET applications and it Works ok until this instance shoots the cpu usage to very high 80 to 100%. At this moment the instance can not work properly and logically all our programs gives TIMEOUT ERROR and it occurs until we restart the instance...

Our .NET programs call web services and wait for the information, we can not do anything there and we can not debug the instance (this is a exe program developed by Microsoft), then what can I do? Can somebody help me I do not know what to do...

Thank you very much.

Hi,

This sounds like there is a bug in the NAV code that is causing this performance issue.
If you start NAV development environment you can debug NAV code and check waht is wrong.

You can also use Visual studio to debug NAV too, you have to start Visual studio debugger and link it to NAV process this will show the code in C#. For that reason i think the first option with NAV development environment is easier and more helpful

I hope this helps.

You have to change the amount of data it's requesting on your .net program. If you ask for a large amount of data that requires processing, it will take up all of the resource.
