Strange RAM Memory issue

[rod]

I happen to note, thanks to the new graph, that my RT-N16 with.44 firmware starts with 60 Mb free and slowly starts to loose free RAM... in a matter of minutes there will be 6 mb or so.

I have stopped most of the entware's services (except for aria2 which is idle right now) and it stills happen. Right now the output of free is:
admin@RT-N16:/tmp/home/root# free

admin@RT-N16:/tmp/home/root# free
             total         used         free       shared      buffers
Mem:        126452       119352         7100            0         4220
-/+ buffers:             115132        11320
Swap:            0            0            0

I dont know how to track it of find that pacman proccess

Here is the output of ps

Any pointer or advice is highly apreciated.

Fixed reinstalling entware from scratch

After a clean entware install the free memory is 50 mb. Even with aria2 running.
----
After some time, even after a clean router restart, it will fill all the ram (with no files downloading nor seeding in aria2 queue)
