First: I got the same problem when using scp to copy files from cdrom to harddisc.
Second: After the failing attempt to copy the data, its not possible to browse the cdrom via thunar anymore. It seems to be seeking but obviously kind of lost the connection to the device. So i guess its not o problem of memory allocation. -- usb flash memory hangs after copying few MB https://launchpad.net/bugs/17881 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
