A dedicated server client of mine was telling me that his mysql was corrupted frequently and when his admin tried to upgrade his php and mysql he faced segmentation error. His admin was saying that this was a RAM problem. Is it possible? Frankly in 11 years of hosting I had not heard of such. If not what could possibly cause the segmentation errors?
In my experience, when a server starts segmentation faulting when compiling applications it usually is a bad stick of RAM. I've had this happen many times and replacing all of the sticks of RAM resolved the problem.
Why replace all of the sticks of RAM? If it's a production server, it's not always feasible to spend an hour or so testing each individual stick of RAM... it just makes more sense to replace them all in one go, and test the previous RAM "offline" so to speak.
If you have IP-KVM switched to your server, then you can run memtest yourself. Otherwise you need to have your NOC technicians to run it for you. If memtest fails, then the problem is with your RAM and it needs to be replaced.
