UPDATE: There's a dedicated test in master branch group_tmp_file_cleanup.js, however, it starts to fail only with memoryLimitMb >= 15.
This seems to be a fairly general issue, because the following simple test reproduces the problem:
function repro() {
db.c.drop()
print("inserting")
doc = {x: "x".repeat(1000)}
many = Array(1000).fill(doc)
for (var i = 0; i < 100; i++)
db.c.insertMany(many)
print("aggregating")
r = db.c.aggregate([
{
$group: {
"_id": "$_id",
x: {$push: "$x"},
}
}
], {
allowDiskUse: true
})
}
