Re: Linux choosing to swap despite having 250G of file memory available

[Frits Hoogland <frits.hoogland@xxxxxxxxx>]

Thanks for your response. I do understand your reply, and what your point at.

The question really that I have is if there is logical scenario where this swapping scenario could happen.

All the documentation and what I see in the source suggests that in cases like this the file memory should be used.

Thank you,

4.18 was released in 2018.  I know Red Hat still supports it, but really
that's up to them.  You need to engage with Red Hat product support,
not upstream.  We don't know what changes Red Hat have made to it that
may influence swapping behaviour.
