No Veritas Stack information Found in crashdump.

Advised customer to open a case with OS Vendor.

OS Vendor confirmed that the root cause for the issue is U block corruption. The U-block area of the process which is getting created is in corrupted state, which resulted in system crash while operating on the process address space during exec.

This issue can be worked around by tuning the following tunable:

# vmo -r -o vmm_mpsize_support=2

This issue can be fixed by applying the APAR IV99101.

Note :  Do not Ask Customer to Apply the APAR without confirmation with IBM Support.
