If all the Virtual Memory (VM = RAM+SWAP) is exhausted the kernel will |

"So, the kernel mistakenly attacks the biggest VM-hog of a process it |
| 13 |
can find, which is generally your X server if you happen to be running |
| 14 |
one. So, your X server dies, and the root cause of the low-VM condition |
| 15 |
(tmpfs) isn't addressed. Ick." |
