./uxshw cal mu=* EXP

.

.

Segmentation fault

Environment

Product:  CA Automic Dollar Universe v7.01.01 and AIX 7.x

Operating System: AIX 7.x

Cause

This is a limitation of 32-bit applications: SIGSEGV/SIGILL crashes on 32-bit AIX applications most often stem from insufficient memory in their addressing
scheme. A collision occurs on the stack/data pair when MAXDATA is too low.

Resolution

Workaround:  With Dollar Universe version is 7.01.01 or lower, please define variable before running the command(uxshw cal).

LDR_CNTRL=MAXDATA=0x80000000
export LDR_CNTRL

 

Solution:

Please upgrade to Dollar Universe Application Server v7.0.1.11.
