maybe too many loop mounts? Try to create a few new loop devices.

modules.conf:

options loop max_loop=256

# mknod -m 660 /dev/loop8 b 7 8
# mknod -m 660 /dev/loop9 b 7 9
# mknod -m 660 /dev/loop10 b 7 10

or just:

# for ((i=8;i<=$ANZAHL;i+=1)); do mknod -m 660 /dev/loop$i b 7 $i; done


# if loop is compiled into the kernel, than you have to add to the Linux
 Kernel line:

module /boot/vmlinuz max_loop=256 ....
