z/VM 5.3 has a Rexx STSI() function. TSO Rexx does not, even at z/OS
1.9. Running APF-authorized this code (or something like it):
MODESET MODE=SUP
SLR 0,0
STSI 0(0)
MODESET MODE=PROB
should return a '3000'
You might want to search the IBMVM archives for LDUBUF/STORBUF and SRM
settings. Sounds like you may have guests in the 'E3' queue.
