I added the option
sysrc savecore="YES"

And unpacked the debug kernel on the target machine.
# env LANG=en_EN.UTF-8 ls -l /usr/lib/debug/boot/kernel/kernel.debug
-r--r--r--  1 root  wheel  122662424 Jan  9 06:11
/usr/lib/debug/boot/kernel/kernel.debug


Changed sysctl option to trigger crashdump
# sysctl net.inet.tcp.cc.algorithm=htcp
net.inet.tcp.cc.algorithm: newreno -> htcp

You need to wait 2-6 days for crashdump to appear...
