Hi Linh,
That looks strange, especially the randomness of this behaviour.
Does user id 7806 correspond to a user?
In your source directory, what is the contents of etc/runguard-config.h? In particular what is the value of "VALID_USERS"?
Could you send a zip file of a judging directory where this error occurred, and also the later rejudging? These are directories of the form judgings/<judgehost>/endpoint-default/cX-sYYY-jZZZ under your judgehost installation directory.
Could you also send the logfile of the judgehost where this occurred?
Best, Jaap

Dear Sir,
I am using Domjudge to set up ACM Contest in my school, everything is OK.
I can submit Java, C, C++ very well.
I also install cgroup and using chroot.
But sometime, I received error like this when I submit any code, just somtimes this happened, and when I rejudge them, I received CORRECT response.
Error text:
Compiling failed with exitcode 255, compiler output: /domjudge/judgehost/bin/runguard: illegal user specified: 7806 Try `/domjudge/judgehost/bin/runguard --help' for more information.
Can you show me how to solve this problem?
And I also run domjudge without root accout, I run it with an account with root privillege!
Thanks. I'm looking forward for your help!
Best regard,
Linh
