(No space left on device) error

hey guys, 

im unable to update twonky and also facing issues in accessing the feature pack application (which is intalled in MBL)

when trying to update twonky i get the following error:

Cannot write to `twonkymedia-powerpc-glibc-2.2.5-6.0.39.zip.1’ (No space left on device).

when trying to access the ‘feature pack’ interface i see the following messages:

Warning : session_start() [function.session-start]: open(/var/lib/php5/sess_64f99d88dec4c8691a00b906222c4723, O_RDWR) failed: No space left on device (28) in /var/www/fpkmgr/inc/_Common_Functions.inc on line 49

 

**Warning: Unknown: open(/var/lib/php5/sess_64f99d88dec4c8691a00b906222c4723, O_RDWR) failed: No space left on device (28) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php5) in Unknown on line 0**

it seems like its gotto do with the system not finding sufficient space (despite my HDD being only 35% used)

my space allocation looks like:

Filesystem            Size  Used Avail Use% Mounted on
/dev/md0              1.9G  1.3G  584M  68% /
tmpfs                  50M     0   50M   0% /lib/init/rw
