Memory issue

[strasharo]

Hello. I'm running the script on a Raspberry Zero running Raspbian 8.0 and Python 2.7.9 The wireless adapter that I'm using is Alfa AWUS036NHA. The script runs fine for a while, except that the memory usage grows up steadily over time and eventually I run out of memory at some point:

pi@zero1:~ $ date;ps -eo size,pid,user,command | awk '{ hr=$1/1024 ; printf("%13.6f Mb ",hr) } { for ( x=4 ; x<=NF ; x++ ) { printf("%s ",$x) } print "" }' | sort | grep python | egrep -vi 'sudo|grep'

Is it a memory leak or something this behavior is expected?

The issue has been fixed. The problem was that scapy was storing packets. Fixed with sniff(..., store=0)

Thanks a lot.
