An established connection was aborted by the software in your host machine

Since moving to CF2016 I've been seeing quite a lot of the error below in the exception log file. I did some research and can't quite figure out what is going on and if this is indeed having an impact on the end user. I've tested the download link on http://www.hiddentoolbox.com and it appears to work fine

"Error","ajp-nio-8016-exec-6","03/26/18","11:55:46","myapp","The cause of this output exception was that: org.apache.catalina.connector.ClientAbortException: java.io.IOException: An established connection was aborted by the software in your host machine. The specific sequence of files included or processed is: C:\ACS\hiddentoolbox\downloadfile.cfm, line: 15 "

coldfusion.tagext.OutputException: The cause of this output exception was that: org.apache.catalina.connector.ClientAbortException: java.io.IOException: An established connection was aborted by the software in your host machine.

I was wondering if this is as simple as people closing their browser before the download is completed, although I could not replicate myself by starting and closing a browser before it had completed.

Could anybody help throw some light on it?

Thanks

Mark

It does indeed work without the CFABORT and plain text, giving this (Will change to this as the right answer)

 

<cftry>
<cfcontent type="application/unknown" file="#downloadlocation#\toolbox.exe" />
<cfcatch>
</cfcatch>
</cftry>

I'd recommend that you remove the CFABORT and the plain text output in your CFCATCH - or at least try that and see if it's happening. I can easily see that breaking some clients downloading your files.

We might be able to throw some light on the matter if shared with us the code that caused the error. Namely:

C:\ACS\hiddentoolbox\downloadfile.cfm, line: 15 

Was it the cfcontent line you posted later?

Here's the code

 

<CFIF #ISDefined('url.aff')# AND #ISDefined('url.sub1')#>
<CFCOOKIE NAME="aff" VALUE="#val(URL.aff)#" expires="never">
<CFCOOKIE NAME="sub1" VALUE="#left(URL.sub1,50)#" expires="never">
</CFIF>

<cfparam name="cookie.aff" default="0">
<cfparam name="cookie.sub1" default="0">


<CFSET downloadfilename = "HiddenToolboxInstaller" & "_a" & "#cookie.aff#" & "_r" & "#left(urldecode(cookie.sub1),50)#">

<cffile action = "append" file = "c:\acs\hiddentoolbox\control\logs\downloadfile_cfm.txt" attributes = "normal" output = "AFF:#cookie.aff# - SUB1:#cookie.sub1# - #now()# - #remote_addr# - #CGI.HTTP_USER_AGENT#">

<cfheader name="Content-Disposition" value="attachment; filename=#downloadfilename#.exe" />
<cfcontent type="application/x-msdownload" file="#downloadlocation#\toolbox.exe" />

I'm going to make a suggestion. I'm not even sure I like this suggestion, but here goes. You might try making your download page unavailable to regular HTTP GET requests. Put it behind a form or something. Your problematic clients probably won't go through the form. And you might be able to capture some useful information along the way.

I took another look at this and it appears to be the use of CFCONTENT.

I have a simple page with:

<cfheader name="Content-Disposition" value="attachment; filename=#downloadfilename#.exe" />

<cfcontent type="application/x-msdownload" file="#downloadlocation#\toolbox.exe" />

The code does function, the EXE is triggered for download, and yet I'm getting all these errors in the log file

Does anybody have any idea why?

We have been seeing this, too.  A lot.  I, also, have not been able to reconcile what is happening.  We have keyword searchable PDFs, and it is always a user clicking on a link to view a PDF that is triggering it.

V/r,

It certainly was not there on CF8. No idea at all what's causing it and I can't find any other posts either.
