OOM Killer

The MonetDB server may become a victim of Linux kernel functionality  called Out Of Memory Killer (or OOM Killer) responsible for dealing with excessive memory requirements.
If the system reaches a point where it may  run out of memory, OOM Killer looks for victim process and ends its life the hard way.

In most cases, a simple restart of the server will suffice, but when the killer enters during a complex update transaction then the database may end-up in an inconsistent state.
