Adobe Reader Closes automatically while the form is large

Question

Hi ,
I am having the application PDF which is stitched dynamically. Here In the PDF user can enter N number of location and corresponding details.
When the Locations is increased then the Data volume also will be increased. and also in the PDf has N number of tabs(Like Home , Help .. etc ) .
We also have some functions like submit , Export XML , Import XMl .....
All the functions are working fine but
when the form is large and user navigates different panel (via clicking the button) the the PDF is closed automatically.
Example : - In the PDF I have two Panel/Tabs Like P1 , P2 . When I clicks,
P1 - Some calcaulation (Reading the data from XML and N Number of loops and calculate value)
P2 - To View the Value based on the P1 calcuation
Problem : -
If user Clicks P2 then calcuation is working Ok and clicks p1 then Adobe Reader Closed.
If User Clicks P2 and clicks P1 then OK but user clicks again p2 and p1 then Adobe Reader Closed.
Adobe Reader automatically closed first time or 2nd or 3rd......
But I having these issue only for Large PDF. Current issue PDF has 6 MB and the exported XML is 2 MB .
Is any Memory issue ??
Any Ideas..??

Hi,
I would say you are definitely coming up against memory restrictions. There are a couple of posts by John Brinkman that I would recommend.
First I would look at why the form is 6Mb and see if you can reduce this down. For example, select fonts that are already in Reader (like Myriad Pro) and then deselect Embed Fonts in the File > Form Properties > Save Options. Also do not embed images into the form. See:

Next look at your script. You mention loops, so check is your script efficient. For example, use xfa.resolveNodes() once outside of the loop, instead of xfa.resolveNode() inside the loop. Make sure that variables are declared. See:

Also check for any script that you have in events that fire frequently, like layout:ready event and comment these out. See.

The dataset seems very large at 2Mb. Does this include image data? It may be that the user is interacting with the form, while it is still trying to process the XML and the loops.
Hope that helps,
