Why is this not being Cached

It appears that I have found the root of my issue. And it was completely by accident. I was browsing the site and found a page that was larger than the Maximum Object size of the default profile(50000 bytes). This returned a "This page it to large to cache" in X-WA-Info. I increased the size to 80000 to see if I could get a page to cache(I also fiddled with the parent profile). And miraculously all the pages that would not cache before started caching. I verified this by setting the profile back to 50000 and sure enough the pages started not caching again.

It appears to be a bug perhaps in X-WA-Info as after putting the number back to 50000 the X-WA-Info once again returned: [V2.S10201.A5777.P45671.N89193.RN0.U3665486284].[OT/html.OG/pages].[P/0.3].[O/0.3].[EH3/0].[DH3/0].[C/P] S10201: Response was served from the origin web server, because the request was for new content.

Setting it back to 80000 and the pages started caching again.

I am running 11.4.1 in a vcmp configuration on v5200's if that matters
