2540 disconnects with "MAC Connection Failed"

I have a 2540 which works very well when my device is put on my table. But if I put it on my body it tend to make sporadic disconnects :S

Based on http://e2e.ti.com/support/low_power_rf/f/538/t/312781.aspx I was able to get this disconnect reason out (which was not listed under Disconnect Reason Code!):

 #define LL_STATUS_ERROR_CONN_TIMING_FAILURE 0x3F // MAC Connection Failed

In CoreSpec 4.0 this is explained with: "MAC Connect Failed—The MAC fails to connect on the selected channel for any reason"

Any clue why this happens when device is put on my body? Most likely a hardware issue as it seems rock stable when put on the table. The software has same behavior in both cases. Any ideas how to address this further?

Thanks :)
