As you have pointed out : "... In fact, it seems that the longer it runs, the longer it takes to terminate (towards 5 seconds after running for a couple of minutes ..." , please run the script a few times : say, before starting up your application, 10 sec. after it's got started, 1 minute, a few minute... http://people.redhat.com/mingo/cfs-scheduler/tools/cfs-debug-info.sh then send us the resulting files.
