Error: spawn EBADF with TeamCity

[jkodroff]

My build fails intermittently on TeamCity 9.0.3 (latest at time of writing) with this message (but never in my command line window):

[16:10:08][Step 1/1] child_process.js:1155
[16:10:08][Step 1/1]     throw errnoException(err, 'spawn');

This is the gulp task:

gulp.task('test', ['restoreSlnPackages', 'build'], function () {
  return gulp
    .src(['src/**/bin/' + configuration + '/*.Tests.dll'], { read: false })
    .pipe(nunit({
      executable: 'src/packages/NUnit.Runners.2.6.4/tools/nunit-console.exe'
    }));
});

It might have something to do with the fact that my nunit executable is in the solution packaged path.

I'm not even sure this is a gulp-nunit-runner issue, but I thought I might report it here in case anyone could shed any light on the situation.

@mikeobrien I don't use TeamCity so I can't troubleshoot this. Since you added the TeamCity reporting, is this something you could take a look at?

[mikeobrien]

I've never seen that before. Sounds like it might be a race condition tho. If you are doing package restore and tests async then I could see that possibly causing this problem.

@jkodroff, were you able to get this resolved on your end? I did notice that it looks like you are restoring packages at the same time you are trying to build (the dependencies run concurrently). You might try using something like https://www.npmjs.com/package/run-sequence to run the tasks sequentially instead of concurrently.
