Hi Jaap

Thanks For your reply and i have subscribed to emaillist

Still the problem is same I have increase MEMRESERVED to 3GB on both files java_javac and java_javac_detect

I have run ./create_cgroups as well and also set grub_cmdline_linux_default = " quiet cgroup_enable=memory" and update grub

still have this error :

sudo ./judgedaemon [Mar 19 13:04:49] judgedaemon[3402]: Judge started on f003 [DOMjudge/5.1.0] [Mar 19 13:04:49] judgedaemon[3402]:*Not using cgroups. Using cgroups is highly recommended.

Not understand how to enable cgroups

My Java programs are not complied although c and C++ programs are working fine.

Thanks Raj Baghel

Hi Raj,

First, please subscribe to this emaillist to make sure that your emails arrive automatically.

To what size did you raise the memory limit? Try to raise it at least to 2GB if you're not using Linux cgroups. Unfortunately, the way that memory is reserved by the JVM and counted (using resource limits) by Linux often requires such huge amounts.

Therefore we strongly recommend using cgroups: that measures only memory really used by the JVM and requires more reasonable overhead.

Best, Jaap
