Missing words in dic file?

[radix]

Hmmm... is your wordlist incremental (ie 0000000000, 0000000001, etc)? If so, try this:

./hashcat-cli64.bin -m 2500 -n 20 cap.hccap -a 3 ?d?d?d?d?d?d?d?d?d?d

Also, you have 20 processors? If not, -n should be the total number of hyperthreads, or number of cores for non hyperthreaded processors.
