Not exactly. You are misinterpreting the output. |

You are using about 341MB = (731 - 164 - 226) MB. About 1MB of your swap is |
20 |
used for whatever reason. Maybe there was a short peak time (memory-wise) |
21 |
when some piece of software got swapped out (actually, paged out) and hasn't |
22 |
been used yet since. |
23 |

24 |
If swap space usage goes up over time monitor your processes using tools like |
25 |
top, ps and such to check which process eats up memory. Then do as I |
26 |
originally suggested. |

|
28 |
BTW, keep in mind that tools like top, ps, free,... are notoriously *wrong* on |
29 |
linux. They give you an idea of memory usage but don't take their exact |
30 |
numbers for truth. Question to the rest of the crowd: Did that change with |
31 |
kernel 2.6? |
