Ok, I think we might be on it now:
D PARMLIB
gets
RESPONSE=S0W1
 IEE251I 17.21.37 PARMLIB DISPLAY 231
  PARMLIB DATA SETS SPECIFIED
  AT IPL
  ENTRY  FLAGS  VOLUME  DATA SET
    1      S    A3CFG1  USER.Z31A.PARMLIB
    2      S    A3CFG1  FEU.Z31A.PARMLIB
    3      S    A3SYS1  ADCD.Z31A.PARMLIB
    4      S    A3RES1  SYS1.PARMLIB
    5      S    VUSER2  VENDOR.PARMLIB
    6      S    VUSER1  SVTSC.PARMLIB
    7      S    VUSER1  LVL0.PARMLIB

And in 
ADCD.Z31A.PARMLIB(SMFPRM00)
and
USER.Z31A.PARMLIB(SMFPRM00)
I found
JWT(0400)
as Jay Maynard predicted!

I changed both to JWT(2400). Short of reIPLing, is there a way to make this 
active? Since it's just me, I *can* reIPL, but I'd sorta rather not--there are 
a bunch of things that have to be started manually, so if there's a command 
it'd be easier.

To find out PARMLIB concatenation order, you can issue - 

D PARMLIB command OR
SDSF and then option PARM and then on the command line type SRCH SMFPRMxx (once 
you know what SMFPRMxx you are using by issuing the D SMF,O or D IPLINFO,SMF 
command)

As for the IEFUTL exit and whether it is in use, you can issue - 

D PROG,EXIT command
