I still saw client cache pressure messages, although I think it did in
general help a bit. What I additionally just did (like 5 minutes ago),
was reduce "mds_recall_max_caps" from 30,000 to 10,000 after looking at
this post:
https://www.spinics.net/lists/ceph-users/msg73188.html
And will try further reducing mds_recall_max_caps if the pressure
messages keep coming up. After reducing it to 10,000 a few client cache
pressure warnings cleared but I don't know yet if that was the reason it
cleared or if it was just luck. If I see it stay clear then I'll call
it solved.

As Dietmar said, VS Code may cause this. Quite funny to read,
actually, because we've been dealing with this issue for over a year,
and yesterday was the very first time Ceph complained about a client
and we saw VS Code's remote stuff running. Coincidence.
I'm holding my breath that the vscode issue is the one affecting us -
I got my users to tweak their vscode configs and the problem seemed to
go away, but I guess I won't consider it 'solved' until a few days
pass without it coming back... :)
I wonder if the vscode configs solved your issues, or if you still see
the cache pressure messages?
