[Live-devel] File size with OpenRTSP

I use a standard kernel on a debian Sarge (2.6.8).
I made this test on the box, look : The file "size_test_100Mo" size is 
98Mo ; at begin, "size_test" size is 0.

# while /bin/true ; do cat size_test_100Mo >> size_test ; ls -lh 
size_test ; sleep 1 ; done

-rw-r--r--  1 root root 2,5G 2006-09-07 09:28 size_test

So there is no problem to generate files bigger than 2Go on the box.

I am quite lost...
