During processing which would have resulted in a SYSABEND, SYSMDUMP or SYSUDUMP dump request, ABDUMP determined that it should not take the dump because a critical resource (QName: SYSZTIOT or SYSIEA01) is held by another task. The environment is such that the other task may never release the resource. ABDUMP generates this SVC dump instead for the stated jobname.
The SVC dump options used are RGN, LPA, TRT, GRSQ and SUBPOOLs 230 and 253.
