The upgrade was done from 9.5.1 which has minimum system requirement of 4GB RAM, so this problem never occurred. The memory was not enough to start all DevTest components, hence the registry was crashing. Verified this by checking the free space after starting all the components. Also CPU utilization showed spikes of high usage with servers started.
Component : CA Application Test
Increase memory on the Server.
System Requirement RAM: 8GB
And for DevTest 10.3 alone the minimum RAM required is 8GB.
