I was also a little surprised. I knew of an 8k output limit but not
that nagios doesn't care about it

1. I already got bad experience with dyn mem allocs and resulting
memleaks
I'm a brandmarked child and just afraid of doing it. Butvalgrind and much testing should solve this
2. Performance and data amount is another point. Since nagios doesn't
build a barrier for insane plugins - I would prefer to build this
before the database.

Opinion registered
Since detecting this kind of bottleneck within ndoutils as a greybox
(for the user) between data collection and data storage I would say +1
but also I see a mob of users with torches and pitchforks after
blasting their tablespaces
