Perforce Maximum Changelist
Perforce P4V Maximum Changelist Number of Files Displayed

But you can modify this limit by changing the “Maximum number of files to be displayed per changelist field:
I would say that such a high number of files in a changelist should be unlikely necessary, specially if you expect someone to review it.
I remember the endless discussions and complaints about Microsoft Excel not able to show more than 32767 lines.
The question is what are you really looking at with such a high number of lines? Wouldn’t that a summary, sorting, consolidation, grouping etc might not help your life easier?
In this case I was making a merging (integration) between two branches and there was more than 4000 lines of code. Then I was looking for some specific area, so I need to browse a few files.
