Mass print performance documents - consolidated output limit?

Summary

Performance documents are missing from the consolidated output

Content

HR Specialist follows these steps:
My Client Groups/ Performance/ Process Mass Actions for Performance Documents/ Add/ Mass Print Performance Documents. We select the review period, performance template and business unit, and then click Submit.  We see the list of results and can download the files individually, but when we choose the "consolidated output" option some of the performance documents that were in the search results are missing. Our pdf consolidated output gives us a maximum 700 pages.

Has anyone else encountered a limit to the number of pages or file size limit in the pdf consolidated output of the "mass print performance documents" task?
