Color Factory running on a virtual server appears to hang when the service is started.
Color Factory memory defragmentation is probably enabled. This will make Color Factory allocate a big chunk of memory when the service starts before releasing it again. Since VMWare does not release the memory, it will remain allocated and could slow down other virtual servers on the host.
Disable memory defagmentation in Color Factory when running on a virtual server:
1) Open the FotoWare Administration Console
2) Click on the Color Factory node and go to the Process environment tab.
3) Select the checkbox labelled Disable memory defragmentation.
4) Save the configuration (Ctrl-S) and restart the Color Factory service.
