Such fragmentation can only occur in batch initiators, or z/OS UNIX initiators, 
aka BPXAS), which are address spaces that are being reused job by job, or UNIX 
process by UNIX process, resp. 


The OP talks about started tasks, and those get a new address space each time 
they are started. Fragmentation leading to S822 might only occur in multistep 
STCs, but even then would I consider it most unlikely.
