Dear All,
I have experienced a memory leakage when i use busybox-1.14.1 on Snapgear
linux( for leon architecture) (kernel 2.6.21.1). I am not quite sure that if
this is a busybox problem or kernel. The problem is as follows:
when we run the following script in busybox (ash) , the memory leak appears ,
and kill all mem at end.
---------------------------------
#!/bin/ash
while [ 1 ];
do
GATEWAY=`iproute | grep default | awk '{print $3}'
done
---------------------------------
Of course we are not going to run this script in an endless loop without
sleep, but we run it in specific periods of time.
Note1: when we run "iproute | grep default " with out awk and GATEWAY variable
THERE IS NO memory leakage.
Note2: when we run "iproute | grep default | awk'{print$3}' without saving it
in GATEWAY variable there is memory leakage.
Note3: when we run "iproute | grep default" and save its out put in GATEWAY
variable THERE IS memory leakage.
we have checked busybox 1.15.3 and we faced the same problem.
Is it a kernel or busybox shell problem?
Thanks in Advance.
