pacclient.py download is not working with larger file #18

I have a file with size 3.7GB, I tried to download the file using pacclient.py and its failing with exist code 137.

root@test:/opt/pacclient# ./pacclient.py download -d ./ -f /home/shabbim1/test/outputs.tar.gz.uu 10170559
Start to download...
Killed
root@test-upload:/opt/pacclient# echo $?
137

I think the issue is related to memory, pacclient is trying to download the file at once rather than in chunks. since it is reading all the content in memory at once, some memory issue is occurring.
