- From: Zdeněk Bělehrádek <zdenek.belehradek@superhosting.cz>

- Message-id: <20150923095125.2437.43810.reportbug@mailer1.startupjobs-1.superhosting.cz>
Package: linux-2.6
Version: 2.6.32-48squeeze10
Severity: important
We have several virtual servers running under Xen, and two of them crash every few hours to days. Crash times are quite random, we have seen two crashes just about 2 minutes apart, and also few days went without crashing.
The crashing servers are used as mailservers, and run several instances of Exim, each listenning on different loopback and public IP address. Our customer uses it to send bulk e-mails, so there are long intervals of inactivity. We do have more of these serevrs, only two of them are crashing.
I checked the core dump with the crash utility, and it always hits kernel BUG: unable to handle kernel paging request, always in the same function and with the same backtrace. The crash is always triggered by collectd process. We tried to update kernel to latest version, and it had no effect.
The hypervisor is xen-hypervisor-4.4-amd64 from Debian Jessie, the Dom0 is also Jessie. There is enough RAM in physical HW to support all the guests and some more.
I censored hostnames and IP addresses to protect the innocent.
