Exhausted?

[Toil]

When I'm running this command:

./hashcat-ocl-64.bin -c 500 --gpu-accel 160 --gpu-loops 1024 -n 800 --remove -m 0 uncracked.txt -o cracked.txt -a 3 -1 ?l?d?s?u?h ?1


I get;


Status.......: Exhausted
Input.Mode...: Mask (?1)
Hash.Target..: File (uncracked.txt)
Hash.Type....: MD5
Time.Running.: 1 sec
Time.Left....: 0 secs
Time.Util....: 1025.5ms/168.4ms Real/CPU, 19.7% idle

Rejected.....: 0/157 (0.00%)
HWMon.GPU.#1.: 35% Util, 45c Temp, 10% Fan

I'm using a 7970, and it works with wordlists, etc, and other masks, with other hash lists.

Any idea why it's happening?


Thanks
