We have a TSM 5.1.7.2 server running under OS/390 2.9 at the moment,
and expected to be running under OS/390 2.10 within the next few days.
We occasionally have a process or session cancelled while waiting for
a tape mount. This triggers a completely useless memory dump from TSM.
The OS/390 console message describing the dump is as follows:

IEA794I SVC DUMP HAS CAPTURED: 463
DUMPID=002 REQUESTED BY JOB (ADSM    )
DUMP TITLE=COMPON=OAM LIBRARY AUTO COMM SERVICE,COMPID=5695-DF1
           80,ISSUER=CBRLLACS

Is there any way to suppress these dumps, either by changing TSM
settings or by using OS/390 PARMLIB members or user exits?
