It sounds like your Linux images are going into the Eligible list instead of the Dispatch list in z/VM. You may have over-committed real storage. Try issuing CP IND Q when this happens to see if any of your Linux images are in the eligible list. If so, you may want to either reduce the size of the Linux images (VM memory on the USER statement in the directory) or use CP SET SRM STORBUF to overcommit storage. Regards, Jim
