In this case, a db.currentOp(true) was issued on a mongos shell. Presumably, this will collect all db.currentOp(true) outputs from the shards, combine them and return the end result.
I'm not sure if there is an easy way to avoid the problem. Perhaps it should only return what can fit in the 16MB document, rather than returning the error message. Or fail gracefully with a better error message.
