Well that doesn't seem right.  It should always play the whole file.
There were some modifications to allow stopping/starting of streaming
files I suppose this could be related.

the 510 Invalid error is generated by app_agi when find_command does not
return a valid command.  Now "STREAM FILE" is a valid command so it should
find that, so would it be possible that you are sending an extra return so
app_agi thinks you are sending an empty command?

You could modify app_agi.c so that find_command prints some extra
debugging of the command it is trying to find.
