Up to this stage, I don’t know it is or not enable
What I'm looking for is actually the line below "webserver group" that says:
- use Linux cgroups...: yes/no
But when I logged in to your machine, /root/domjudge-5.1.1/config.log shows that cgroups are disabled. You have the package installed, but have not edited /etc/default/grub, so the kernel doesn't support cgroups yet.
As a side note, you should not install DOMjudge as root user. Instead create a separate user to install it as: DOMjudge will use 'sudo' to obtain root privileges only when needed.

Did you install or copy runguard to the judgehost installation (under
judgehost/bin)? This step is not explicitly listed in the documentation.
Not yet it is not listed in the document Best

Hi, I do follow exact with the help file and I do up to: -Install the necessary packages: # apt-get install libcgroup-dev (or # yum install libcgroup-devel on RedHat)
- Edit grub config to add memory cgroup and swap accounting to the boot
options. Edit /etc/default/grub and change the default commandline to GRUB_CMDLINE_LINUX_DEFAULT="quiet cgroup_enable=memory swapaccount=1". Then run update-grub and reboot.
-Compile DOMjudge with cgroup support. Re-run ./configure and look for
cgroup in the output.
And did the configure output say that cgroups were enabled?
How to rebuild : Then rebuild the runguard with make build. I only make all after re-run ./configure
Did you install or copy runguard to the judgehost installation (under

Upto that point, then I run ./judgedaemon Then I said no cgroup Best

When you (re)ran configure did it say that cgroups were enabled?
Did you recompile and reinstall runguard (or the whole judgehost
installation)?

Hi Jaap, Can you look at 2 lines : # exec java -client -Xss8m -Xmx${MEMLIMITJAVA}k -DONLINE_JUDGE=1
-DDOMJUDGE=1 '$MAINCLASS'
exec java -client -Xmx3g -DONLINE_JUDGE=1 -DDOMJUDGE=1 '$MAINCLASS' before you change and successfully run, I already change.
I recommend not to change it like that: then if you change the
configured global memory limit, it will not affect Java submissions.
Also, if you now reduce the memory limit below 3 GB, then java
submissions will automatically crash because the JVM is trying to allocate more memory than is allowed by DOMjudge. NOTE: DOMjudge imposes the memory limit onto the whole Java VM, that's why this this whole MEMRESERVED variable is needed in the first place.
