thanks for this reference... it matches pretty much my observations. I 
did a lot of attempts to tune maxvnodes during the last days, but the 
pgdaemon issue remained. Ultimately I suspect it is also responsible for 
the reproducible system lock-ups during ZFS send.

I am about to revert the patch from the PR above on my system and re-try.

Kind regards
Matthias
