I can make new files, folders and install new software but I can't download files from the internet (Using Iceweasel(Firefox) and Midori). When installing new software at some point it says something like "man.db: not enough memory". Also when starting the Pi, "[warn] Root filesystem full...warning" comes up. I use rasbian wheezy with a 16GB SD card. I always use root user. Any ideas what the problem is?
df command output:
Filesystem 1K-blocks Used Available Use% Mounted on rootfs 15328248 15010504 0 100% / /dev/root 15328248 15010504 0 100% / devtmpfs 53720 0 53720 0% /dev tmpfs 12396 252 12144 3% /run tmpfs 5120 0 5120 0% /run/lock tmpfs 24780 0 24780 0% /run/shm /dev/mmcblk0p1 57288 18888 38400 33% /boot tmpfs 24780 8 24772 1% /tmp
