I found a way to see the error messages, and I think I have solved my problem!
For reference, there's some great info on Ben Nadel's blog: http://www.bennadel.com/blog/743-Learning-ColdFusion-8-CFThread-Part-I-Data- Exchange.htm Here's what you do: <cfthread action="run" name="myThread"> Your Thread Code goes here </cfthread> <cfthread action="join" name="myThread"/> <cfdump var="# myThread#" /><cfabort> So, you join the thread and that will cause the code to wait for the thread to finish. Then, you can cfdump the name of the thread and see any output it generated including error messages. The <cfabort> is in there because this was running in a CFC, and otherwise, I would never see the output. My problem was that things running in a cfthread are more sensitive to scope issues. Here's what I had: <cfset personalMessage = "This is personalized for you"> <cfsavecontent variable="eMailBody"> <cfinclude template="pathToTemplate"> </cfsavecontent> The template I was including expected a value for personalMessage. As soon as I explicitly scoped personalMessage like this "variables.personalMessage", the error went away. What's weird is that even though CF didn't know personalMessage was defined it still found it! I defined a <cfparam> in the template so the variable would always be defined. This stopped the error, but even before I explicitly scooped the variable, CF still put the right information into the template. I've been trying to pay attention to scoping variables - I guess this is another reason to do it right! Thanks again everybody for all your help!

What I'm trying to do inside of my <cfthread> is have a loop that for each eMail address: . Creates a personalized eMail . Sends the message with <cfmail> . Waits 1000 ms Using <cflog>, I know the thread is starting, but apparently, I am getting some errors that cause the thread to terminate. Before, I was using <cfsavecontent> and <cfinclude> to assemble my personalized eMail message. The message has a header, a body, and a footer and I have a <cfinclude> for each section. But, <cfthread> and <cfsavecontent> don't seem to want to play nice together. I know cfthread can't send output to the page, but that's not what I'm trying to do. I just want to create my personalized message, save it in a variable, and send it out via <cfmail>. I may also have some path problems with the cfincludes, but even when I comment all that out, everything seems to fail right after the <cfsavecontent>. Has anyone experienced these issues? Do you have any suggestions for me? And, one more question. Is there a way to see error messages that get thrown inside of a thread? This is ending up being trickier than I thought. Oh well!

For one thing, you have to have "start monitoring" enabled, which isn't on by default. Just thought I'd clarify that if it might be the only reason you don't see them. Even then, the threads could run very fast. I'd recommend instead you go old school, and throw a CFLOG into the thread code (and outside the thread code) to write to a file that you can look at to confirm if it's ever written to. /charlie From: ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Clarke Bishop Sent: Wednesday, May 27, 2009 5:52 PM To: discussion@acfug.org Subject: RE: [ACFUG Discuss] Sending large numbers of eMail via ColdFusion Thanks for the ideas Troy, Dawn, and Doug! I decided to try out cfthread as my code was already much like what Troy suggested. Here's what I have now: <cfthread name="sendPR" action="run"> <cfloop query="qEmails"> <cfif qEmails.personalized EQ True> <cfset personalMessage = qEmails.message> <cfelse> <cfset personalMessage = ""> </cfif> <cfset sendMail(qEmails.eMail, subjectMsg, personalMessage, Template)> <cfset sleep(1000)> </cfloop> </cfthread> The only thing is the thread doesn't seem to run. The above code is inside a CFC function, and the sendMail() call goes to another method in the same CFC? I saw an example on the web where someone did this, so I think it's OK. Any ideas what I might be doing wrong? Also, are there good ways to trouble-shoot with cfthread. The code runs correctly when I comment out the cfthread tags. But when they are in there, nothing seems to happen. No thread ever shows up in the Server Monitor.
