We are trying to debug some issues with our ColdFusion installation and decided
to revert our JVM settings back to their original state. According to a
technote, these are the settings we should use:

technote:
http://kb.adobe.com/selfservice/viewContent.do?externalId=ce138b7a&sliceId=1

java.args=-server -DJINTEGRA_NATIVE_MODE -DJINTEGRA_PREFETCH_ENUMS -Xmx1024m
-Dsun.io.useCanonCaches=false -XX:MaxPermSize=512m
-Dcoldfusion.rootDir={application.home}/../
-Dcoldfusion.libPath={application.home}/../lib -XX:+UseParallelGC
-Dcoldfusion.classPath={application.home}/../lib/updates,{application.home}/../l
ib/,{application.home}/../gateway/lib/,{application.home}/../wwwroot/WEB-INF/cff
orm/jars

The problem is that CF won't start with these settings. I found that if I
removed the MaxPermSize setting, CF would start with no problem.

Since our original issue was memory related, I'd like to know why the server
would not start with the MaxPermSize setting in place. Is this a deprecated
setting? Any help would be appreciated.

Environment:
CF7.0.2
Win2K Server
JVM: 1.4.2_15

Ours is set to "128m" - which is the default for CFMX 7.0.2 I believe.

Was 512m too large for your environment perhaps?
I would try adding the setting back into the JVM args, and changing it to 128m
to see if that works.

Also, be very aware of extra newline or whitespace characters in your JVM arg
list. It is easy to get confused if you're editing the args via the <textarea>
provided by the JRun console. I personally prefer to manually edit the
jvm.config file, located here:
.....\JRun4\bin\jvm.config

That did the trick, thanks.
