I just install ACS 5.3 on a VM.
VM Spec: ESX 4.1, 2 CPU, 2GB ram, 100GB HD, 1GB NIC
After installation, when I do "show application status acs", it always show "Application initializing..." after couple hours.
I had reboot it couple times, no help.
I have attached acs support and show tech file.
Thank you very much for your help!
