Lizette, As Scott mentioned, when running in star mode, you may see a CPU spike on the GRS contention notifying system (CNS) when there is a resource contention in the sysplex and the CNS has to issue ENF 51.
Try checking whether the system you noticed the CPU spike on is the CNS using a D GRS command. If it is in fact the CNS, you may choose to assign the role a CNS to a different system in the sysplex. You can do that using the SETGRS CNS= command (introduced in z/OS V1R8 i believe). Gil.
