PDF overall limit?

Hi =)

I'm working with LiveCycle ES4 on a pdf that has now 2,29 MB. Is it too much?

I have a lot of code written in javaScript.

I'm asking this because now I have unexplained errors in the code.

The "same" code works in some places and doesn't work in others. Is this a thing? LiveCycle has a limit?

Thanks =)
