The error occurred during soak testing of build '20151113' (see https://wiki.hpdd.intel.com/pages/viewpage.action?title=Soak+Testing+on+Lola&spaceKey=Releases#SoakTestingonLola-20151113) and earlier already when testing build '20151109'.
DNE is enabled. OSTs had been formatted using zfs, MDTs using ldiskfs. MDS nodes are configured in HA active-active failover configuration.
At three moments in time:
| date |

the oom - killer had been invoked on the nodes specified. (All events happened at times where no fault was injected.)
Attached files: console and syslog of nodes affected.
Unfortunately collectl wasn't running to gather performance counters.
The tool has been enabled on all soak nodes to be able get memory, especially slab stats during one of the next sessions.
