Dear xwiki-users,
 
We are getting a Java exception when saving a 7MB attachment.  The attachment appears to be attached properly, since it appears in the attachment list and can be downloaded after the error.  However, after attaching four or five files the server becomes so unresponsive that a restart is required.  Configuration Info:
 
OS: Windows 2000 Server
RAM: 1GB
JDK: 1.5.0_8
App Server: JBoss 4.0.4
Database: MySQL 4.1.21
 
Note that JBoss is run with -Xmx 512M, and increasing that to -Xmx 1024M has no effect.
 
I've gone through the attachment documentation and mailing list archives and didn't see any references to a similar problem.  Any help would be appreciated - I plan to checkout the code and see what's happening!
 
Here is the stack trace:
