On an UNIX system, when too many users belong to the same group (in /etc/group), the DUAS jobs will abort.
Release : 6.8
Component : DOLLAR UNIVERSE
System limit
Use different group names with the same GID (Group ID).
Eg :
TOOL (GDI 101) : 2000 users
TOOL1 (GDI 101) : 2000 users
Because the GDI is the same, the permission will work the exact same way for both groups.
