Hi Remco,

We have purchased a double XEON 12C server for a total of 48 logical CPUs machine dedicated to NCrunch. The sad news is that we need to manually open/close Grid Node configuration on remote server almost daily because it's impossible to connect to it after some time you are using it. I mean, we use it succesfully for a day or two, then when we go back to unit testing we find it missing. The same is true for a different PC we use as server as well.

We own 8 NCrunch licenses.

Do you know why or what we need to check to resolve this?

Thanks,

Alberto

Hi Alberto,

The only thing I can think that the grid node configuration tool might be doing here is restarting the grid node service. So probably restarting the service yourself would have the same effect.

Do you experience the same thing if you run the grid node using NCrunch.GridNode.Console.exe instead of the service process?

Hi Remco,

Do you mean that the next time I get into this problem, instead of doing Start/Programs/NCrunch Grid Node Configuration and close it, I need to run NCrunch.GridNode.Console.exe console program from "C:\Program Files (x86)\Remco Software\NCrunch Grid Node Server" folder?

Thanks,

Alberto

Hi Remco, hi Alberto.

We have had the same or at least a similar problem with our grid nodes. After disabling the NIC power management on the nodes NCrunch is running fine so far.

Have a nice weekend!

By default, the grid node server is hosted as a service under windows.

It doesn't have to be this way. You can also run it as a console application. This will give more visibility into its workings and also give you greater control over it.

Nonetheless, Thomas' suggestion is really good one. NIC/Power-management could mess with the listening ports opened by the server. Make sure you have this disabled.

Thanks Thomas,

I will try this settings the next time the NCrunch server is stopped.
