When scripts/vm/hypervisor/kvm/kvmvmactivity.sh is called with an incorrect file name, an error is printed which is then interpreted as output from the script. When an incorrect file name is passed the script prints out: stat: cannot stat ‘b51d7336-d964-44ee-be60-bf62783dabc’: No such file or directory =====> DEAD <====== The KVMHAVMActivityChecker.java checkingHB() process is expecting just =====> DEAD <====== but gets the unexpected error message and interprets the file as alive.
