[BioC] density plot of pm values

Hello BioC Users,

I have a problem interpreting my data.
I am analyzing my microarray data and did a density plot of my pm values
for the six arrays.

I am getting a strange behavior of these arrays. Instead of getting one
peak for the data as it is usually is ( at least as fat as I know it), I am
getting two peaks (see the image attached).
The good news is that they all behave similarly, so it might be normal, but
I just don't get it.

I would appreciate any ideas as to the rasons behind this behavior.
