well cat /sys/kernel/mm/transparent_hugepage/defrag
always [defer] defer+madvise madvise never
was active now since your reply, however, I can not tell that it helped.
This was set on 2 hosts, one has 20GB of unused RAM now.
Yesterday there was a similar picture for both, with several GB, one with
up to 10GB unused,
I just checked once, this is what I recall.
tell me if one would like to login remotely, I can set up teamviewer or
something for this
at any time, just drop a message here and I'll contact you.
I have hopes that one can investigate things even on that host that has
20GB unused, it's just
a matter of time until this gets to the low values, surely the problem here
already kicked in.
Also if the remote login is not an option, I'm always happy to provide
whatever info you need.
