Insufficient memory available

i am trying to do a test with hashcat 6.2.5 on my The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) linux. 
when i am running the command: 
hashcat (v2.5) startin
hashcat -O -w 4 -m 1000 --username -a 0 -r  ~/hashcat1/hashes-ntml ~/hashcat1/crackstation.txt.gz 

it is giving me error as follows: 
hashcat (v6.2.5) starting
