Invalid form token. Please reload this form and submit again.

Permalink 19 15 Browser Info Environment
Clean empty install of 8.1.0 using theme Elemental.
Adding 5 file upload fields to a new form gives the error "Invalid form token. Please reload this form and submit again." once the files have uploaded. The files are png files, under 1MB each.
The files do not exceed the post_max_size, max_file_uploads, max_file_size, max_execution_time set in php.ini
But uploading just 2 or 3 files means the form submits correctly.
This is a somewhat cryptic message that does not return anything useful when I Google it.
