ASM log warning message

This happens on very large content typically exceeding 50Mb. If your application has a webpage which has a size of 50Mb you have a special case (can you imagine how long it will take to be displayed on user's browser?)

You can increase the limit if you need to.

This is described in support article: https://support.f5.com/csp/article/K42301022

However I recommend you talk to your application development team first to see if such massive application responses are legitimate as this could potentially be a sign of an attack or some other problem.

The reason why F5 limits the response buffer to 50Mb by default is to protect the memory on your F5 device

Hope this helps,
