Hello,

I hope I won't be bothering with dumb question, but I wasn't able to find any solution to my problem...

I'm playing with LTP, and it works nice for me (few tests fail, but with obvious reasons, which I will fix,
so this is Ok), but I'm having problem with memcg_stress test. It always almost immediately gets host machine to
heavy swapping, and never finishes... when I had 2GB of swap, machine usually got into totally unusable state,
when I lowered swap to 512M, I'm at least able to kill test after some time...
I guess this is not expected behaviour, but my question is, what should I check to get this working properly?
I'm getting same results for latest x86_64 2.6.32.x and 3.0.x. Testing machine has 4 cores and 4GB of RAM.

Could somebody help me with that please?

with best regards
