dual core issue?
by Jamie Levy
Hello,
I was just running Volatility on a couple of Linux boxes and received quite
different results. I have tested this on two other boxes to verify the
results and it seems to be a dual core issue.
Here is the expected output on a single core system:
$ cat /proc/version
Linux version 2.6.22.9-91.fc7
$ python -V
Python 2.5
$ Volatility-1.1.1/volatility pslist -f image.vmem

And here is the output from a dual core system:
$ cat /proc/version

The above errors on the dual system have been observed on a dual core laptop
running Ubuntu as well... I was wondering if others have seen this, and if
there is a work around yet?
