It is a mixed TPF(4.2 - not Z/TPF) guests / VPARS / CMS workload. Naturally, TPF guests are the heaviest users. I have seen this sort of problem before when we have streaming output from one of the TPF guests that has filled all the CP spool or IUCV buffers and I have also seen it when DITTO goes into a loop of retries after running off the end of a tape. I have also seen it when there are huge despatch queues due to very heavy processor load. None of these seem to be the case at the moment.
