Dear Sir,
-- With my problem: +++ First: I make judgehost: make judgehost +++ I found error: gcc -fPIE -Wl,-z,relro -Wl,-z,now runguard.o /usr/lib/libm.so -o runguard /usr/lib/libm.so: could not read symbols: File in wrong format
+++ So, I run gcc -fPIE -Wl,-z,relro -Wl,-z,now runguard.o /usr/lib64/libm.so -o runguard ==> No error anymore
+++ Afterthat, I run make judgehost again to make sure that without any error was raise. +++ Final, I run: make install-judgehost withour any error
-- About cgroup: I will check this, if I get any problem, I will contact you, thank you so much!
Best regard, Linh

I solved this problem, now I can run contest throughly! Everything is OK.
great! Can you please describe how you solved the problem (for future reference)?
But I have a question: I run domserver and judgehost on a same server.
So when I start judgedaemon on server, problems submitted will be
compiled.
So I want to ask that if I can create many judgedaemon on this server?
And
how can I do this? Because some problems has longer executive time.
I only can remote connect to VPS via ssh, and my server is:
-- 16CPU Xeon -- Ram 12GB.
So can you give me some suggestion for my contest!
Did you enable cgroups as described in the manual? https://www.domjudge.org/docs/admin-manual-3.html#ss3.17
With cgroups (and after the creation of multiple run users), you can start multiple judgedaemons on one machine. Make sure, you have enough resources left for Apache and mysql on the server machine.
Cheers, Tobi
