Environment:Windows, Unix as well as far as I can tell.
Trying to do something like that:
function drainCursor(cursor, targetCollection, perf) {
function iterate() {
return cursor.next()
.then(function (item) {
if (!event) {
cursor.close();
return;
}
return targetCollection.insertOne(item)
.then(() => iterate())
.catch(err => {
Logger.error(err);
throw err;
});
});
}
return iterate();
}
Getting the exception after about 1000 records processed (actual number looks random).

Used to work fine, but not with the latest drivers (tried 3.0.6 and 3.1.1, 3.1.1 appears to crash even sooner)
After some googling this is how i make a cursor, but it doesn't help either.
sourceCollection.find(Query).addCursorFlag('noCursorTimeout', true).maxTimeMS(0),
Originally I would run multiple threads of this (on different collections) but it crashes much sooner in this case.
