I tried os.flush() as you recommended previously, it did not work. I
even set large chunks and did System.gc() in the loop, that didn't
work. Then I even tried putting the System.gc() after I close the
connection, but the heap still remains quite large.
When I transfer a bunch photos (say, 50 for example) I see the heap
grow occasionally but shrink again staying within 5-8M. When sending 2
videos I can get the first one to work, but the heap never shrinks
down low enough before the next video tries to send and I get the
error. Granted, that is a moot point as any single large video would
fail and I need support for any large file.
Thanks!
