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. See the manual for details.*

http://localhost/api/
[Mar 19 13:04:49] judgedaemon[3402]: No submissions in queue (for
endpoint default), waiting...


Not understand how to enable cgroups

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


Thanks

    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
