In some case, the cache is too small. (2GB)

1. Log in to the vCenter Server UI
2. Click on the hamburger on the top left and select Auto Deploy
3. Click on Configure
4. Click EDIT under VMware Image Builder Service section
5. Change the value of cacheSize_GB from 2 to 4 and restart Imagebuilder service in VAMI

Alternatively, below commands can also be used to increase Imagebuilder cache size:
sed -i 's/cacheSize_GB=.*/cacheSize_GB=4/' /etc/vmware-imagebuilder/sca-config/imagebuilder-config.props
service-control --restart vmware-imagebuilder
