[NCrunch Console Tool v3.9.0.1]

Got this error (NUnit tests) on TeamCity today (am about to upgrade to 3.10.0.6 in order to keep versions in sync with my vstudio2017 version).
Code:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I've seen this also, rarely, on a heavyweight grid node.

It may take me time to track it down. I had hoped I was the only one seeing it. I guess you just crushed that delusion :(

A reset of the client or grid node always gets rid of it.

Ok thanks, this case should not have been involving any grid nodes though, and it didn't re-appear after upgrading (usage of NCrunch with this heavy project on TeamCity is still in the "experimental" phase so it isn't executed very often).

Hrm I take that back, now the build reported successful but with 0 tests run, looking into build log I see

And after that it seem to spend 15 minutes to just call LocalAnalysisTask and LocalBuildTask to grid nodes :/

The socket related issue above is essentially a noise exception that can happen if the connection is suddenly closed without warning. This won't be related to the earlier problem you've reported, but it does make sense that this could slow things down for your test run. A disconnection means that the grid client needs to resynchronise with remote grid nodes, which on a large solution can sometimes take a little while. There are some improvements here coming as part of the 3.10 release that haven't been included in any publicly available builds (yet).
