Bloat in MVS_ADDRSPACE_T
If you find this table growing very (unmanageably) large, look
for rows where SUBSYSTEM_ID is null. This occurs when SYSOUTs
are spooled or spun-off to other systems, including TSO XMIT,
RJE, and files sent to VM. The rows are generated by extra
SMF Type 26 records. Most fields in these rows will be empty.
There will usually be no point in keeping these rows beyond
2 days after they've been created.
Execute DEFS(PURADDRN) to remove them, or PURADDRT in the normal
purge job.
