Default ERS2500 Hardware error ---- Tucana MMU DRAM CG0.M0 CRC error----

Im having problem with my ers2500 switches which encountering this error show whenever you connect to the console.

Tucana MMU DRAM CG0.M0 CRC error at 0x00005381
Tucana MMU DRAM CG0.M0 CRC error at 0x00005380
Tucana MMU DRAM CG0.M0 CRC error at 0x000053fb
Tucana MMU DRAM CG0.M0 CRC error at 0x000053f9
Tucana MMU DRAM CG0.M0 CRC error at 0x000053f8
Tucana MMU DRAM CG0.M0 CRC error at 0x000053f7

Once this occurs I will receive excessive timeouts when I ping the switch IP and will receive complaints from users that the application are having problems.
When I reboot the switch I see this error.
Test ROM Config - PASSED
Test BCM565X Registers - PASSED
Test PHY Registers - PASSED
Test Internal Loopback - FAILED
Loopback error bitmap 19DBCD00000

Is this some hardware problem known to ers2500 because Im having more than 10 switches encountered this problem and in just two weeks I have 4 switches having this problem as well? Im worried that this might happen to the rest of my ers2500...
