this error is produced by an audio codec when the buffer it is given
to output data too, is too small. For instance, lets say you are
encoding and you provided a buffer that was 500bytes big to contain a
single encoded packet, but the encoder produced a buffer that was
600bytes - this would generate that error (there's a few cases of this
in the codecs, so its not that easy to pinpoint exactly what the
problem could be)
I don't know why this would be an issue on the server though - umm...
perhaps the server has a different version of QT (the audio codecs are
distributed with QT), and so you are hitting a discrepancy between two
different versions of the audio codecs. So check that...

I'm hoping someone can point me in the right direction for fixing a
problem that has me completely baffled.
On a Leopard Server with 10.5.7, I'm getting the following error
from running the afconvert tool in Terminal to convert an aif to an
mp4: Error: ExtAudioFileWrite failed ('!buf').
If I run afconvert on my MBP (also 10.5.7 in the Terminal) going
over the network to the same file on the server, the conversion
works perfectly - so the files are OK.
When I'm on the server, I can write into the folder with the audio
files - so the permissions seem set properly.
I can't find any explanation for the '!buf' error message, so I'm
not sure what afconvert is hiccuping over.
I really know almost nothing about the whole ACL permission scheme
on the server, but is this something that could cause the error
message? Any other directions I should be looking in?
