But they are related.  Raising the limit is the alternative to this PR, for most users most of the time.
I think it was reasonable to ask what kind of size are you seeing, and with what kind of frequency.
That should help say whether this is a bump the limit situation, or a we-must-fix-this-now situation.

JDK-8319055 says we should rework this in a better way, which I expect we all agree on, and this current PR is a possible solution until that change comes along (which might be undone by JDK-8319055).

/proc/pid/maps was > 2GB of text?  At that point nobody can help you. 8-)
If that maps list ended before showing the high numbers, nobody would be surprised!
