Hi, thanks for posting.

There are two different exceptions thrown here. One is related to connectivity, and is known to be caused by unexpected disconnection with a grid node. This is essentially a 'noise' exception, as the client will always reconnect when this happens. There are some improvements coming for the connectivity code with the upcoming v3.10 release.

The second exception is more mysterious. I have a feeling this might be caused by .cache file corruption. Would you be able to try clearing out your NCrunch cache file on the machine running the console tool to see if this resolves the problem?

Thanks for the quick feedback, Remco.

I had time today to look into it and delete the cache. Unfortunately it did not help - although I am not sure if it is the same issue:

Hi, this does look like the same issue. We have at least one test here that is somehow disassociated with all the projects in your solution, so it's basically floating around disconnected. This could be due to something going wrong in the startup process, or cache data corruption, or possibly something related to the structure of one of the tests.

I'm presently not aware of any way that a test can reach this state. I've seen similar reports from other users, but deleting the .cache file always fixed it and the problem has not yet been reproduced.

It may be quite hard to track this down.

Do you have this problem appearing only when using the console tool? Does it appear for you in the NCrunch VS client too?
