** Description changed: Hi there, I've upgraded a number of test systems to the latest Saucy beta. I've seen quite a few cases of processes being killed by lowmemorykiller with the following entries being logged: [ 291.565121] lowmemorykiller: send sigkill to 4476 (python), adj 0, size 8864 [23515.006794] lowmemorykiller: send sigkill to 944 (update-apt-xapi), adj 0, size 44175 The systems where this happens are kvm virtual machines with relatively modest amounts of RAM allocated (256 or 512 MB) with 2 GB swap. The swap is mostly unused when the kills occur. I searched around and could only find references to Android for lowmemorykiller and nothing on how to disable it.
