The following error is generated when trying to use cfhtmltopdf function on the page:

 

Error Occurred While Processing Request
Error occurred while generating PDF.
Reason: Error occurred while handling request.

 

- the page gets successfully generated if the <cfhtmltopdf> tags are removed

- the request generated a lot of data, which is roughly 1200 A4 pages

 

Is there a limit on the file size/number of pages when using the <cfhtmltopdf> tag?

Wow, that's a lot of pages! I don't know if there's a strict file size limit, but you may simply be exceeding the available memory you need. I suggest trying a smaller number of pages per request, then merging them together after you've got them all.

There might be something else bothering your application.

 

I did some tests to generate a 1400-page PDF. The execution times were as follows:

 

119 seconds

<cfdocument format="PDF" filename="C:\Users\BKBK\Desktop\largeDoc.pdf">	
	<cfset i=1>
    <cfloop condition="i lte 1400">
	    <cfset i=i+1>
		
		<cfdocumentitem type = "footer"> Footer text <cfoutput>#cfdocument.currentpagenumber#</cfoutput></cfdocumentitem> 
		<cfdocumentitem type = "pagebreak" /> 
    </cfloop>
</cfdocument>

 

12 seconds

<cfhtmltopdf destination="C:\Users\BKBK\Desktop\largeDoc.pdf" overwrite="true">
<cfset i=1>
    <cfloop condition="i lte 1400">
	    <cfset i=i+1>
	    <cfhtmltopdfitem type="header">Page: _PAGENUMBER of _LASTPAGENUMBER</cfhtmltopdfitem>		
		<cfhtmltopdfitem type = "footer"> Footer text _PAGENUMBER</cfhtmltopdfitem> 
		<cfhtmltopdfitem type = "pagebreak" /> 
	 </cfloop>
</cfhtmltopdf>

Thank you for the replies. I will try to change the way that the pdf is produced by adding the destination parameter and see if that works.
