I have one VF page from where I am trying to download some attachments - The time I tried to download attachments which includes Attachments of size 4 MB+ size, it start showing me this error.
Exception : Apex Heap Size too large : 123454
It work fine in the Unlimited Edition.
I get that this is a Heap Size issue explained here
I want to avoid getting this error message, i.e. I want to reset or reduce my Heap Size . Please provide me some suggestions or Example using which I can get it done.
