About 8 to 10 of our servers suffered from these issues in the last days. All servers are virtualized on a vSphere cluster. It happens with amd64 and i386 machines. Our sole non-virtualized server with Debian 8 and linux-image-3.16.0-8-amd64 (Nagios under heavy load) runs stable until now.
One of the affected servers crashes reproducible only a few seconds after the boot process. I thought, this would be a good candidate for trying the fixed kernel from > https://people.debian.org/~benh/packages/jessie-security/ Unfortunately this server (Subversion/Apache) runs a i386 system and the one provided kernel is an amd64 package.
