1.For many entries in data groups better use external data group:

2.Another thing is to enable logging at different level to see if you requests match the irule at different stages:

3.Also as note with your version you can try to use F5 Local Traffic policies as they support data groups and are less buggy or CPU intensive than iRules:

4.The final thing is to look the bug tracker if you checked everything like the irule matching the traffic, etc. You searc by "data group" and see if you match a bug:
