I am running httperf client on my m/c and after few seconds it is getting killed. dmesg shows:

The command is:

httperf --hog --client=0/1 --server=39.0.0.2 --port=80 --uri=/50kb --rate=20000 --send-buffer=4096 --recv-buffer=16384 --num-conns=6000000 --num-calls=1

Although I had done this test no. of times but never faced this error any time. From last two days I am observing this.

My Ubuntu version is ubuntu 10.04. and httperf version is httperf-0.9.0
