Hello Bernhard, thank you for your hints, I can try with VBox 4.1, but first I will try to get rid of the Ext2 from my system. On another machine I have switched to UFS2 and the speed increased noticably. I will let you know when I transfer all of those GB of data :-) Yes it looks like the cause of the hangup is the swap rush/deadlock but I could not verify it as the machine was unresponsive. Still both machines use 1GB of RAM per VM so still 2GB should be free. With other applications running and the OS taking 1GB itself (what I have seen on some other posts) this may happen :-( Best regards :-) Tomek --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
