Subject Re: [Axis2] MTOM Large file sending problem
Date Fri, 14 Jul 2006 05:01:48 GMT
Samuel,
These days I'm doing some MTOM testing with very large attachments (>500mb),
to find out if there are any defects with larger files.

Have you tried by increasing the time out..For that u need the latest svn
head.. (Checkout taken in last couple of weeks would be fine)...
