Hmm apologies I'm stumped then. The only things I managed to surmise from xgboost's and scikit-learn's GitHub issues is that this is a recurring issue specifically when using GridSearchCV :

Threads with discussions on workarounds:

Issues reported: (this looks quite similar to your issue)

Some quick workarounds I saw were:
1. Remove n_jobs argument from GridSearchCV
2. Use parallel_backend from sklearn.externals.joblib rather than concurrent.futures so that the pools from both libraries don't have weird interactions.

I recommend opening an issue on scikit-learn/XGBoost's GitHub. This seems like a common problem that they face.
