We are experiencing crashes on our SSD VPSes, all working on KVM: crashes occur for different reasons; in the hurry to restore the service my team uses to reload a previous snapshot of the machine and never saves the logs.
Anyway, among all the different crashes circumstances, a recurring fact is the
corruption of in-memory data: our VPS provider told us their hardware is running fine, yet I don't know how to read the poor log I was given.
What is involved when an "in-memory data corruption" is detected? Could it be because of broken RAM, or there are other kinds of memory corruption?
Funny thing: a VPS provider using VMware never gave us troubles, the one using KVM is really driving us crazy because of these crashes.
Edit 1: I, by no means, demand that you people deduce the solution from this miserable log. I'm stuck with this issue where no decent log is provided,
memtest is useless since the hardware is emulated and the VPS provider granted that their hardware is fine and no instances of KVM or QEMU crashed.
corruption of in-memory data detected is haunting me, and I can't think of any productive approach to investigate further this issue.
