I can confirm this for the S510 as well - which didn't show any I/O error
but is really slow. I can also confirm that using "-B" solves the issue
with 1.0.21. Here is my list of tests using the ScanSnap S510:

I just did a quick git testing.
The buffer problem seems to be solved now.

Thanks for the testing guys. Looks like this one is squashed.
For the record, the problem was caused by code I added to reduce the
memory usage of the backend.
Sane backends 1.0.20 and before used a full-size buffer for both front
and backside data. Total of 200Mb for 600dpi color duplex A4. 1.0.
I just did some benchmarkung it takes 18 seconds to scan a A4 600DPI
color duplex page.
4878*7046 600DPI 24bit color on windows. And 1 minute or more on linux
if I use scanimage like this "scanimage -b -B -d fujitsu --source "ADF
Duplex" --mode color --resolution 600" it seems to work.

Hello allen,
300dpi always ok.
I try it with 600dpi:
- ubuntu 10.04 32bit -> ok
- ubuntu 10.10 64bit -> not ok
not ok: scan stops at half page.
ok:

what version of sane-backends is that? Can you also try a test at 600 dpi?

No, Markus has uncovered a real bug. The S1500 chokes when doing high
resolution duplex scans. The backend reads data from both sides of the
paper, and buffers the back side. Unfortunately, we read too far ahead
on the backside, and the scanner has problems.
Do you have the S1500 too? perhaps you
Please try the following:
SANE_DEBUG_FUJITSU=25 scanadf -d fujitsu --source "ADF Duplex" --mode
color 2>S1500.log
then send me S1500.log directly.
