Abend 0C4 UFSD

[robprins]

Hi,
I started UFSD with an authorized STEPLIB.
I met a 0C4 abend with code 4 (protection).

I have attached the dump
These are 3 dumps of 3 startups of USFD.
The 2nd and 3rd dump are dumps were UFSD are defined in the RAKF user table.

Please advise,

Cheers,
Rob

It looks like, that the APF authorization causes the abend. Removing the authorization fixes the problem.
Possible due to SVC 244. With SVC 244, you can set the APF bit in the JSCB of the jobstep TCB.
I think that the APF bit is not checked before issuing SVC 244. SVC 244 should only be issued if the APF bit is NOT on.
