Just grabbed a couple things off related problems. Can you give these look? No guarantees.
1. ...stack size (kbytes, -s) 8192
819200 or higher should work.
2. ARS_ICOS_FORCE_COMPLIANCE=0 parameter, add to ars.icos config file
3. Current CMOD NonProd server/client are on 10.5.0.1.
Both need to be upgrade to 10.5.0.2 and then apply PH37296 fix.
