    Problem running rtcheck on RT kernel

    Hi I am using SLES 11 with RT kernel.
    I tried to run (as root) the rtcheck -v and got the following error:
    RTCheck 0.7.6 - Linux Real-Time Environment Checker
    RTCheck Initialization:
      Locking all memory: ok
      Setting up real-time scheduling: ok
    System Tests:
      Looking up boot_id (378798aa-d760-4d89-a52b-fecc5941127a): ok
      Checking for out-of-tree RT extensions: ok
      Checking for robust (PI) mutex support: ok
      Testing for acceptable hrtimer resolution (<=100us): ok
    	Reporting 53us
      Testing for acceptable clock resolution (<=200us): ok
    	Reporting 1ns
      Caching results in /var/cache/rtcheck: ok
    User Permission Tests:
      Trying to lock memory: failed
    	RLIMIT_MLOCK is: 65536
    Some tests failed, exiting with status: 1
    It looks like some permissions issue, but I couldn't find any guide which explains how to solve this problem.
    Does anyone know how to set the proper permissions to run RT on this OS?
