Nice day to everybody. Several days ago I have downloaded newest AOS distribution for Linux revision 5294 dated April 4th 2013, but after installing and running aos a window with white background opens in linux and nothing more happens. Linux console is outputting following text: Machine.ExpandHeap: posix_memalign: Cannot allocate memory LinuxAos (rev.5294): Kernel: Initialized and started. X11 Display depth = 24 All previous distributions worked fine. I have 2MB of RAM but never experienced any problems running aos. Zdenek
