- You need swap space for 2 reasons:
-
- 1) to swap to
-
- 2) to write out a dump in case of a panic and crash
-
- If you are running your system with some processes swapped and your
- system comes down, and your swap space is not at least equal to the
- size of swapped processes and the amount of memory you have, your
- panic dump will happily write over the end of your swap space and
- into your next filesystem.
-
- Pick a swap space size that accommodates both of the above, at least
- 1.5 X memory, maybe 2 X.
