Hello guys,

I've run into the situation when a response message from mongodb had length 17947035 bytes. But the driver limits incoming messages by 16777216 bytes. It's apparent that mongodb can return larger documents than the driver can process.

This strange limit is defined in connection.js:

// Retrieve the message size
var sizeOfMessage = binaryutils.decodeUInt32(data, 0);
// If we have a negative sizeOfMessage emit error and return
if(sizeOfMessage < 0 || sizeOfMessage > self.maxBsonSize) {

Shouldn't this limit be lifted to correspond to real mongodb capabilities?

And one more thing. Error message looked like this:

Error: connection closed due to parseError

The message is very unhelpful, I had a long debugging session to get to the real reason of the problem.

Shouldn't the message be updated to point to the real reason of the error?

Thanks,
Evgeny
