I've kept some large files (aroung 100MB) inside /docroot folder. But when i try to download those files from multiple clients (3 to 5 downloads at a time) the server becomes slow and throws the following error:
[#|2009-05-13T13:57:47.000+1000|WARNING|sun-appserver9.1|javax.enterprise.system.stream.err|_ThreadID=33;_ThreadName=httpSSLWorkerThread-8080-9;_RequestID=1220cf44-418a-4dfb-ad63-92739a782bc4;|

I am using the following setup:

glassfish: v2_b58c
JVM settings:
<jvm-options>-XX:MaxPermSize=192m</jvm-options>

Can anyone help me out to understand why i'm getting this error and if there is any possible workaround of this. Is there any other way to host large files in this server.
Thanks heaps.
