    SubjectRe: oom-killings, but I'm not out of memory!
    I think I'm having the same issue.

    I've 2 systems with 4GB of RAM and 2GB of swap that kill processes when
    they get a lot of disk I/O. I've attached the full dmesg output which
    includes portions where it killed stuff despite having massive amounts of
    free memory.
