RE: [Echo-list] File upload - out of memory

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi Felix,

50M might not be quite enough.  I would try upping the heap size to 256M
and see if it solves the problem.  I'm not suggesting this as the
solution, just curious to see if the problem is "not enough memory" or
if the the file upload piece is malfunctioning such that it will simply
take all available memory and then some.

If I recall correctly, a JVM running a good-sized Echo app will use
about 16 megs or so by default (I could be off on that though).  So if
you have a 17 meg file going up, you might easily break out of 50M if
you (for example) had to have two copies of it in memory momentarily.

Best regards
