We have a mongodb instance 3.2.10 running on machine with 4gb ram.
I created 700k documents with the string X in them (X is of length 6 character).
When i run textual query of the type:
db.MyCollection.find({$text: {$search: 'X'}})
We see that the memory raises by 800mb.
After running such a query 3-4 consequential times the mongodb instance is automatically restarted.

This prevents us from using the textual indexing feature in production.
Any workaround? Can we disable the query cache for such queries?
