When using Bulk Check-Out why do I get the error "Error: Invalid port value for "-useca" parameter: machine:port"?
This occurs when your cache agent is listening on a port number
higher than 32767.
If you can easily lower your cache agent port then set it to a port lower than 32767.
If you require the cache agent to listen on a port higher than 32767 then you should download the latest version of the Cross-Platform Client, as this version fixes the issue with BCO using high port numbers.
