Hello,
for testing the bandwidth of my server I downloaded some large files from it. I can reproduce that with a file size of about 100 MB glassfish runs out of heap space. This happens with glassfish on Linux with the out-of-the-box configuration.
This is the stack trace in server.log:

This is not a real problem for me currently as I don't have such large files, but nevertheless I find it strange that the file size is relevant.
Regards
Stephan
