EXCEPTION: NSt8ios_base7failureE non-canonical ReadCompactSize() bitcoin in ProcessMessages() #6746

I have a standard build of bitcoin core 11.0. It has been running for months, and all the sudden it is throwing the following exception. What causes the following error?

One of the peers you are connected to sent you garbage.

There's no actual error.

I was notified about this exception, and I think this issue should be reopened.

Even if it is not a bad state, it appears to cause quite a bit of confusion, and a more user-faced message should be written to the log.
