I am unable to find exact reason for this error over internet.

Hi,please find my explanation

Hi,

please find my explanation below:

%DEV_SELENE-DFC2-3-SRAM_ECC: Selene 0 SRAM High Single-bit ECC error, error status: 0x400182505

Selene is a chip to bridge between two NPU, which connects to GE interfaces each, and
Metropolis, which in turn connects to the fabric. 
The error message indicates that the ingress low priority FIFO queue of the first Selene
experience an ECC error.  If there is only one ECC error, the linecard can correct the
error. If there are multiple ECC errors on the same packet, the packet will be dropped and
that refers to HW failure on the module. 

Try reseating the module once if in case you happen to see the error again after reseating then go ahead and replace the same.
