Multiple NAVISION Application Servers stopping randomly RRS feed

  • Question

  • Hi all,

    Our company has been using NAV 2013 R2 for more than a year now without any server issues. Recently, we were advised to create additional NAV application servers to distribute the load of users connecting. The new NAV server instances runs on separate window server installations. But upon deployment of the servers, we started encountering errors randomly across the three servers and causes the instances to stop. We isolated the issue and found that the errors randomly occur when 2 or more servers are running simultaneously. 

    Our IT already raised this to our provider and they too were unable to troubleshoot the problem. I was hoping that someone here already encountered the error and was able to troubleshoot the issue. The error usually is as follows:

    Application: Microsoft.Dynamics.Nav.Server.exe
    Framework Version: v4.0.30319
    Description: The process was terminated due to an unhandled exception.
    Exception Info: Microsoft.Dynamics.Nav.Types.Exceptions.NavCSideException

    Thanks in advance!
