Hi,

This message comes due to size of the files.  It looks like Email Services provides an entry point that allows developers to push in data sizes that far exceed the heap limits. The regex seems to be failing because of the heap supporting the regex. The only alternative is to cut the file sizes down or choose another integration approach.

 

For more detail follow the below link:

Did this answer your question? If not, let me know what didn't work, or if so, please mark it solved.

Hi,

 

I had the same issue when I tried to process a CSV file of nearly 4MB. But I couldn't ask customers to send me smaller files, so I had to find another way to do it.

 

Finally I developed a Batch Apex process with a custom Iterator. For futher information: http://developer.financialforce.com/customizations/importing-large-csv-files-via-batch-apex/

 

I hope this helps.

I took the FinancialForce code, which is a really good solution, and gave it a once over.  Apex Row Iteration Class post.
