This looks like an extent being added to the library in the middle...
except that your primary allocation only rules that out.

Actually, issuing $PJES2,ABEND and then restarting it, isn't that
disruptive if your JES2 starts up reasonably quickly. The only effect
that users will notice is that their SUBMITs and LOGONswill take a bit
longer.

Looks like you've done everything right here...what's in
SYS1.EBE.PROCLIB? Hopefully, not much. You might run the BLKSIZE
parameter on the first card up to 20480, just to take better advantage
of the pages allocated to the buffers, but that's a nit.

Good question. Has me stumped. I guess you've APARed it...
