How to check the memory on the server?

Question

Debian

Very often (once an hour) lines flies into the syslog:

 kernel:[ 1873.150274] [Hardware Error]: cache level: L3/GEN, mem/io: MEM, mem-tx: RD, part-proc: SRC (no timeout)

In this connection, the question, as I understand it, is the problem in memory? How can I check if it is ECC?

Answer 1

If possible, run through memtester. Here, however, the grandmother said in two - the memory can correct the broken data and the error will not reach memtest.
In general, the ECC is for that and the ECC, so that the administrator does not bother with memory errors, they even write to you:
So my personal verdict: don't pay attention. If programs suddenly start to crash and the kernel panics, then pay attention.
