Memory Leak Looping cfmodule inside cffunction
- by orangepips
Hoping someone else can confirm or tell me what I'm doing wrong. I am able to consistently reproduce an OOM running by calling the file oom.cfm (shown below). Using jconsole I am able to see the request consumes memory and never releases it until complete. The issue appears to be calling <cfmodule> inside of <cffunction>, where if I comment out the <cfmodule> call things are garbage collected while the request is running.
ColdFusion version: 9,0,1,274733
JVM Arguments
java.home=C:/Program Files/Java/jdk1.6.0_18
java.args=-server -Xms768m -Xmx768m -Dsun.io.useCanonCaches=false -XX:MaxPermSize=512m -XX:+UseParallelGC -Xbatch -Dcoldfusion.rootDir={application.home}/ -Djava.security.policy={application.home}/servers/41ep8/cfusion.ear/cfusion.war/WEB-INF/cfusion/lib/coldfusion.policy -Djava.security.auth.policy={application.home}/servers/41ep8/cfusion.ear/cfusion.war/WEB-INF/cfusion/lib/neo_jaas.policy -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=56033
Test Case
oom.cfm (this calls template.cfm below)
<cffunction name="fun" output="false" access="public" returntype="any" hint="">
<cfset var local = structNew()/>
<!--- comment out cfmodule and no OOM --->
<cfmodule template="template.cfm">
</cffunction>
<cfset size = 1000 * 200>
<cfloop from="1" to="#size#" index="idx">
<cfset fun()>
<cfif NOT idx mod 1000>
<cflog file="se-err" text="#idx# of #size#">
</cfif>
</cfloop>
template.cfm
<!--- I am empty! --->
