OK. I forgot run *bin/judgedaemon* again.
Now judgehost work but complie alway error with message:

Compiling failed with exitcode 255, compiler output:
/opt/domjudge/judgehost/bin/runguard: creating cgroup: Failed to
remove a non-empty group(50029)
Try `/opt/domjudge/judgehost/bin/runguard --help' for more information.
Error: failed to set
/sys/fs/cgroup/memory/domjudge/dj_cgroup_30296/memory.memsw.limit_in_bytes:
Cgroup, requested group parameter does not exist


I see a post here:
https://www.domjudge.org/pipermail/domjudge-devel/2015-March/001628.html
But same. I did run the create_cgroups script. I see
/cgroup/memory/domjudge and /cgroup/cpuset/domjudge, so that looks good.
Before i change grup:

GRUB_CMDLINE_LINUX_DEFAULT="quiet cgroup_enable=memory swapaccount=1"

and reboot ok, no errors or anything.
I chek kernel command line: cat /proc/cmdline
But it show: BOOT_IMAGE=/boot/vmlinuz-4.4.0-1044-aws
root=UUID=512611f4-b05a-4d8a-b743-438b71c5385d ro console=tty1 console=ttyS0
