Title: cfdocument crashes/hangs server with many pages	BugID: 1367	Date Opened: 15-May-07
Created By: Joe Gooch Philadelphia Pennsylvania CFUG	Type: Tag	Element/Element: cfdocument
	Severity: Crashes CF Server	Status: New/Unvalidated
	Adobe BugID:

Description of bug:
If a document is generated that is over 400-500 pages, cfdocument fails. It can frequently happen with fewer pages, as the memory issue seems to be cumulative. The code should probably use a virtualizer somewhere to free up memory. (just a guess based on load) Depending on your memory, machine, JVM, etc it is indeterminate how many pages it will take. This defaults to 500, but if that doesn't work, try more. For cfdocument to be viable for report generation, I would expect the ability to generate an unlimited amount of pages without crashing the server, even if an error has to be generated. Example code (a little long): <cfparam name="URL.SCHEDULES" default="500" /> <cfsetting requesttimeout="300" /> <cfset school_start_period = 0 /> <cfset schooL_end_period=10/> <cfheader name="Content-Disposition" value="inline; filename=reportbreak2.pdf" /> <cfdocument format="pdf" margintop="1.2"> <cfloop index="sortedIndex" from="1" to="#URL.SCHEDULES#"> <cfdocumentsection>  <cfdocumentitem type="header">  <table border="0" cellspacing="0" style="width: 100%;"> <tr><td><div class="header2">Student Schedule</div></td></tr> <tr> <td> <table class="headerTable1" style="width: 100%;"> <tr> <td>District:</td> <td>THS</td> <td>School:</td> <td>Test high School (92)</td> </tr> <tr> <td>School Year:</td> <td>2006</td> <td>Semester:</td> <td>Fall</td> </tr> <tr> <td>ID:</td> <td><cfoutput>#sortedIndex#</cfoutput></td> <td>Student:</td> <td>Joe Schmoe</td> </tr> <tr> <td>Homeroom:</td> <td>Homeroom Code</td> <td>Grade:</td> <td>12</td> </tr> </table> <td> </tr> </table> </cfdocumentitem> <table border="0" cellspacing="0" class="scheduleBlock" style="width: 100%"> <tr> <th style="width:25px;"> </th> <cfloop index="day" from="1" to="6"> <th>Day <cfoutput>#day#</cfoutput></th> </cfloop> </tr> <cfloop index="period" from="#schooL_start_period#" to="#school_end_period#"> <tr> <td><cfoutput>#period#</cfoutput></td> <cfloop index="day" from="1" to="6"> <td> <div class="course"> <div class="scheduleTitle">Adv. History</div> <div class="scheduleID">H220-1</div> <div class="scheduleTeacher">Mr. Smith</div> <div class="scheduleRoom">A420</div> </div> </td> </cfloop> </tr> </cfloop> </table> </cfdocumentsection> </cfloop> </cfdocument> </body></html>

Problem still occurs in Scorpio public beta, but seems to be a little better, mainly because it takes less time to generate and uses less ram. Bump up the pages by other 500 or so and the problem happens again.

So it seems the general methods used in cfdocument haven't changed significantly (i.e. no virtualization) however the efficiency of the tag has improved.
