System getting hanged during software checklist in Ax 2012

Problem:

Do you have any ideas to solve with AX hanging when I start "Marge code automatically" in SOFTWARE UPDATE CHECKLIST
(It's just updating AX 2012 R2 to AX 2012 R2 CU7)
It's screenshot with stage on which I have hangs:
Checklist

Solution:

During checklist system generate log at database side . Need to check whether disk space is enough at the time of process.

Check Memory utilization at database side and AOS Side.

There should be enough RAM on database side.

Check kernal and application version it should be same.

Check batch group is attached in proper batch server.
