   <cfscript>         newslettercampaigngateway = createobject("component", "legacy.ssl.admin.news.model.newslettercampaigngateway");         newsletterlist = newslettercampaigngateway.getnewslettersdueforsend();         //writedump(newsletterlist);abort;      </cfscript>     <cfloop query="newsletterlist" >     <cfset newsletterid =  newsletterlist.newsletterid>     <cfset campid =  newsletterlist.id>     <cfset fromemail =  newsletterlist.fromemail>      <!--- <cfdump var="#campid#"> --->     <cfthread action="run" name="runcampaign#campid#" >         <cflock             name="runcampaign_#campid#_lock"             type="exclusive"             timeout="60">             <!--- <cfdump var="#campid#"> --->             <cfscript>                       httpservice = new http();                  httpservice.setmethod("get");                  httpservice.setcharset("utf-8");                  httpservice.seturl("http://mysamplesite.com/legacy/ssl/admin/news/model/newslettercampaign.cfc");                  httpservice.addparam(type="url",name="method",value="sendcampaignnewsletters");                  httpservice.addparam(type="url",name="live",value="true");                  httpservice.addparam(type="url",name="campaignid",value="#campid#");                  httpservice.addparam(type="url",name="newsletterid",value="#newsletterid#");                  httpservice.addparam(type="url",name="fromemail",value="#fromemail#");                  httpservice.send();             </cfscript>          </cflock>     </cfthread>    </cfloop>       <cfloop query="newsletterlist" >              <cfthread             action="join"             name="runcampaign#campid#"             />     </cfloop> 

any idea guys?

well, decided not use cfhttp , used threading , works.

<cfsetting requesttimeout="300000"> <cfscript>     newslettercampaigngateway = createobject("component", "path.to.cfc");     newsletterlist = newslettercampaigngateway.getnewslettersdueforsend(); </cfscript>     <cfloop query="newsletterlist" >      <cftry>         <cfthread action="run" name="runcampaign#url.campaignid#" >             <cfset sendrequest(url)>         </cfthread>      <cfcatch>         <cfdump var="#cfcatch#"><cfabort>     </cfcatch>     </cftry>    </cfloop>  <cffunction name="sendrequest">     <cfargument name="urlstu" required="true">      <cfset newslettercampaign = createobject("component", "path.to.cfc")>     <cfset newslettercampaign.sendcampaignnewsletters(arguments.urlstu)>  </cffunction>
