We set the buffer to minimum and the program worked!

I suggest that you keep your buffer settings (from the preference menu)
set to the minimum values. Unless you are running on a 64 bit linux
system you probably won't derive any additional benefit from having
higher settings and it may in fact hinder performance.

I recently ran a 353 array HG-U133 Plus 2.0 dataset on the windows build
with no problems (using the minimum settings).

Hi Lana,

I have used RMAexpress to process ~180 arrays (also HGU133 Plus2.0) in
my desktop. The version I used was 0.4.1 Release. I don't know where
the problem is, but just want to let you know that it was perfectly
fine in my case.
