One suggestion is to make sure that housekeeping commands are issued *only* on the busiest member of the MAS. He's the one most likely to want the checkpoint frequently, hence the most likely to complain if it's busy.
Another suggestion is to isolate JESCKPT1 on its own volume to minimize RESERVE/RELEASE contention. . .

Just try to schedule it at the time there is the least impact and if it is a shared spool also from a system that has capacity. Hopefully JES2 runs in SYSSTC.
