Hello,
I have an application which uses CFFILE to read a binary file into a variable,
and that variable is used to write out the video to the brower so someone can
download it...
This code is working great, until the file sizes become too large. It seems to
stop working (and returns a null null or 500 null error) when the file sizes go
past 200-250MB...
There are some files on this server that are up to 1GB in size that have to be
downloaded via this script, so it needs to be able to handle pretty big files.
The server is MX7, 4GB Ram, and here are my java args:
java.args=-server -DJINTEGRA_NATIVE_MODE -DJINTEGRA_PREFETCH_ENUMS -Xms1024m
-Xmx1024m -Dsun.io.useCanonCaches=false -XX:MaxPermSize=512m
-XX:PermSize=64m -Dcoldfusion.rootDir={application.home}/../
-Dcoldfusion.libPath={application.home}/../lib -XX:+UseConcMarkSweepGC
-XX:+UseParNewGC
-XX:NewSize=48m
-Dcoldfusion.classPath={application.home}/../lib/updates,{application.home}/../lib,{application.home}/../gateway/lib/,{application.home}/../wwwroot/WEB-INF/cfform/jars
Any help would be appreciated!
Thanks!
