Transferring large amounts of data

I'm transferring a large amount of data between two servers and it was transferring fine for about 2 hours and now it just decided to take a nap... says it'll retry at a certain time, but that time is long passed by.

Why does this happen? How can I prevent it?

Please post the system information from the menu: Help->About "System Information" dialog. Maybe you have reached the max retry?

Regards,
Mat

Needed to change the Max Retry Value to no limit.

Go to Favorites --> Favorites Properties --> Edit Default Favorite (Bottom left) --> Integrity --> Transfer Integrity --> Set to 0 (zero) for no limit.

I guess I never ran into this before because I've never had to move this much data.

Thanks for your help mb!!
