--- Comment #13 from Billg <alaa.alassafin at card-1.com> ---
I'm having the same behavior with freeBSD 11.2 p8. Although swap partition is
not on zfs, we do however have a zfs pool on this machine as described here :
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235125

I tried memphage

total memory is 128GB 
Free memory at the time I started the memphage was 110 GB
Swap 8GB

./memphage 115000 took around 3 minutes with no issues.swap got 3.2 GB filled.

./memphage 120000 took 5 minutes and got killed at 118672Mb

swap was completely filled and got multiple :
Jan 23 14:56:27 san2 kernel: swap_pager_getswapspace(2): failed

and then memphage got killed.

Jan 23 14:56:48 san2 kernel: pid 6945 (memphage), uid 0, was killed: out of
swap space
Jan 23 14:56:48 san2 kernel: Jan 23 14:56:48 san2 kernel: pid 6945 (memphage),
uid 0, was killed: out of swap space

--
No other processes were killed this time. only memphage
