yeah that's what I wonder. I already ran memtester. But (it may be the reason) it crashed the server and owner asked not to run it again. I confirmed with him that he has replaced the RAM a week back and already the entire server itself.

Results of running memtester on 1024 out of the total 2048 gave me the following results. mapcount went negative here, which I doubted corrupt RAM and that's why asked owner about the RAM replacement and he said he did it.

last line is what I got, before it crashed.
