Why can't I produce a PXX dump for DB Return Code xx?

Issue/Introduction
We have a production job that terminated with a DVW RC=22(025) but I cannot figure out what element is bad or missing. Trying to look at this error in the PXX. Where did my PXX go to? (Note: I am not using the SYSOUT MUF startup option)
I did the following:
1) Executed COMM OPTION=ALTER,RCERROR=22025,MASTERL=YES,BUFFERS=YES
2) I reran the job
3) Did a PXX Report with :REPORT AREA=PXX,DUMPS=FULL,JOBNAME=PBLJB093,RTNCODE=22
and it ultimately generated:
PXX END, PXX NOT CLOSED (MUF STILL ENABLED OR PXX WAS FULL AT EOJ) 0/00/0000 0.00.00
Environment
Datacom/AD 15.1
Datacom/DB 15.1
Cause
Normally, if you are not using the SYSOUT option, a snap DUMP would be written to the PXX (which requires executing a DBUTLTY PXX report to read the output). Since a RCERROR was done to overwrite the default parameter for master list dump (M) and master list dump with buffers (B), a system DUMP was taken. Buffer dumps are very large with the use of 64-bit memory for both the index and data areas and the Mult-User Facility (MUF) handles this most efficiently by requesting a system dump (IPCS) of z/OS
Resolution
Regardless of whether the SYSOUT or PXX is used to view RC xx, If the default master list dump with buffers column (B) parameter is changed, a system DUMP will be created. Reasoning behind the default setting of 'N' for column (B) is that, most of the time, it will be a user error. There could be rare instances where Datacom R&D will require you to send in a DUMP if all options have been exhausted or if the R&D team suspect that a code problem might be the issue
[NOTE: best practice recommends that you use SYSOUT instead of a physical PXX]
