Hi

that usually means a memory errors

check sh diagnostic result fex 101...see if it returns ok status

xxxxxxxxxxx# sh diagnostic result fex 101

Hi,

have you found  solution to this issue?

I have similar errors in log and  suspect memory/cpu problems.

I have run sh processes cpu history on fex and found high workload.

Hi Asim,

This is not a software issue. This error means that a single-bit ECC correction (error correction) was made on FEX SDRAM memory.
It is harmless because hardware was able to correct the memory error via ECC. There's a counter that tracks these corrections:

prt> show new_ints

| SS9 : ssx_int_err_ecc1 |
|--+---------+----------------------------------+
|6 |000000050 | single-bit ECC error | main memory bank 1
|-----------------------------------------------|

If this is recurring then FEX should be replaced.
