you might just hit a thrashing situation. Linux is very bad when it |
| 46 |
comes to abusing swap in case of an emergency. |
| 47 |
|
| 48 |
But it also sounds like overheating or a power problem. Power problems |
| 49 |
might be caused by the PSU - but it could also be the power circuitry of |
| 50 |
your mobo. |
