Memory Single Bit Error

Good Day! I'm enccounterring single bit error on my rp8400 server. Anybody have an idea how can i clear this error. Is this critical? what is the impact of this error on my server/system?

Replace the bad memory?

Depends on what you call critical. How
important are your data?

You're wasting time and disk space handling
and logging the errors, and, while ECC memory
can correct single bit errors, it normally
can only _detect_ two-bit errors, so most
people would elect to replace the failing
memory module before it gets worse (and data
loss becomes more likely).

When posting ITRC forum links, it would be
good to remove the useless bits, like "11" or
"12" from the host name, and all the
(cookie-like) "admit=XXX" stuff, so:

Read my comments here:


Short summery:

- update online diagnostics
- reboot the server
- monitor the errors

Hope this helps!

Re: Memory Single Bit Error

Single-bit memory errors are usually fine until the system starts to de-allocate the memory due to too many of them. I would suggest monitoring STM, and eyeballing which set of DIMMs de-allocate.

Just my 4c worth.

Re: Memory Single Bit Error

Might these errors be the result of


It's a lot of them and across the board, most of them on 0/3 DIMM 2D.

If so does that mean the memory was not compatible between the two machines? Or was it bad handling during the transfer?
