5548 Switch Stack Crash

Hello,

I'm running a pair of 5548's stacked.    I'm seeing the switches crash occasionally with this error message:

27-Jul-2013 12:42:03 :%OS-F-MEMORY: OSMEMG_rn_free: Memory magic is invalid

I'm running the latest software:

       Unit             SW version         Boot version         HW version
------------------- ------------------- ------------------- -------------------
         1               4.1.0.10            1.0.0.14            00.00.02
         2               4.1.0.10            1.0.0.14            00.00.02

Anyone have any suggestions?   I've got better logging in place now, so when it crashes again, hopefully I have more detail I can post on it.

Thank you.
