The only thing I have notice is i see the error message:
Jan 2 00:21:23 cstats[589]: Problem loading /mnt/NAS_60GB/asusfolder/tomato_cstats_c86000d2ddc0.gz. Still trying..
The file is there and i have tried deleting it and restarting a new one via the tools page
You need two files! In your case:
tomato_cstats_c86000d2ddc0.gz
AND
tomato_rstats_c86000d2ddc0.gz
Otherwise you will see no "per divice" data.
I had the same problem here.
