As some know, I've had occasions where some program would eat up a lot |
20 |
of memory. I've had a time or two where I had to shutdown or it crashed |
21 |
itself. The offender varies. Once it was Firefox, huge problem there |
22 |
but seems OK now. Right now, sddm is going off the end. For that |
23 |
reason, I actually increased my swap space. It gets really slow to |
24 |
respond when it uses swap but it beats crashing. Just set swapiness to |
25 |
a low number. I think mine is set to 10. |

Given the cheapness of hard drives, I'm not sure why having several |
28 |
gigabytes of swap space is of much concern. I have the same amount of |
29 |
ram as you and I have a 12GB swap space. I use LVM so I can grow it if |
30 |
needed or just add another swap space. I might add, I've seen times |
31 |
where it gets used. |

If you have not had swap touched in a very long time, maybe it is safe |
34 |
enough. Just keep in mind that if some package consumes way more than |
35 |
it should, it can end badly. The kernel's OOM tool isn't that great in |
36 |
my experience. Sometimes it does OK, sometimes not. A couple times, it |
37 |
seemed to not do anything and I got a reboot. |
