Explanation

The package settings result in too many product formats being packaged. In other words, TitleLeaf can’t create a package with that many assets in it. Most often, this is because the resultant package file would be too large (> 5 GB) or it would take too long to create (> 1 hour). The limit itself depends on your specific TitleLeaf instance, a setting named “Package Item Limit” (Admin > Management > Settings > Package).

Solution

Break your package into multiple, smaller packages. For example, instead of trying to package 3 years of ebooks, create packages for each individual year (ie, 3 smaller packages).
