The mix up here between header size and content length is puzzling here. When a client POSTs a large file, it's part of the HTTP body which is defined here:

https://www.rfc-editor.org/rfc/rfc9112.html#name-message-body

HTTP Headers are the other part of an HTTP message, and appear before the body.

Do you have any sample content, or sample error messages from /var/log/ltm or /var/log/apm when these requests are unexpectedly denied by big-ip?
