Rel1k`s Artillery Burst Memory
Greetings Fellas
Couple of months ago I bought an OpenVZ VPS 128mb and installed artillery on it ( https://www.trustedsec.com/downloads/artillery/).
I was stunned with the quality and usability of the particular anti-DoS/Bruteforce attack tool.
A week ago i decided to buy one more OVZ VPS 128 but frome a different company. I installed artillery but once I tried to run the program i got the following error:
Code:
python artillery.py

I contacted the support team of my VPS provider and they stated:
Quote:
According to /proc/user_beancounters you've hit your memory limit 20 times. Keep in mind that even though you have 256MB of RAM, only 128MB is guaranteed and the memory management will not allow a single process to exceed 128MB
|
I argued with them and tried to explain them that only my 7% of my memory is occupied and tried to explain them that on my other VPS, artillery runs smoothly without any issues. The final outcome of the support was:
Quote:
It looks like you're hitting your burstable RAM limit (privvmpages). I have tried the script myself on your VPS and it is indeed causing the count to go up each time. I don't know the application you are trying to run but I would recommend contacting the developer to find out how to lower the RAM usage.
I am attaching a screenshot of your script running and your memory jumping to 225MB of RAM.

the screenshot can be find here: http://tinypic.com/r/zn0sv8/6
For me is very wired and I cant understand how is possible two edifferent VPS (on different companies) with exaclty same same specs, one cannot run artillery and one can.
I was hopping someone here that uses the particular tool to confirm that such issue indeed occurs by the requirements of artillery.
Any ideas, solutions?
