Crate soft nproc 2048 too low

CrateDB Documentation
1

When I set the nproc to 2048 (as recommended in the docs: https://crate.io/docs/crate/guide/en/latest/admin/bootstrap-checks.html), I get the following:

[2019-08-06T10:40:04,085][ERROR][o.e.b.BootstrapProxy     ] [Schrammacher] node validation exception
[1] bootstrap checks failed
[1]: max number of threads [2048] for user [bamboo] is too low, increase to at least [4096]

Once I’ve increased the nproc to 4096 the Crate.IO starts up correctly.

Can you pleas clarify if this is just an oversight in the docs or some other problem?

Thanks

Yes you’re right, the guide is outdated and the expected minimum nproc value must be 4096 for CrateDB versions >= 3.0.0. We’ll update our guide. Thanks for bringing this up!
