Memory usage
OS: Linux Mandrake 9.0
Kernel: 2.4.20
Soltek SL-75DRV5
512MB DDR
Althon XP2100+
I'm noticing memory usage that I cannot trace back to a process - alot of it too. I use top and the "M" command to list programs by memory usage - but what I see with it (or using other system monitoring tools) are only a few processes and none that can explain the memory usage.
Even dropping down to runlevel 1 still displays RAM usage in excess of 300MB. Maybe I've still got alot to spare but I still want to fix this problem - currently running BlackBox under X (I use some KDE apps, but even after killing off all kdeinit processes the memory usage stays high).
So, what would be the cause of this mysterious memory usage?

Where are you "noticing" this memory usage? If it is in the "Mem:" line in top, probably all you are seeing is the kernel's use of RAM as cache and buffer. In slightly simplified form, when a process finishes running, or a file closes, the kernel leaves it in memory **if** it does not need that memorr for something else. (This way, it can run or open faster if called again.)
As a result, *any* Linux system will over time approach 100% memory usage as reported by this measure. If you want to check use of RAM by active processes, run "free" and look at the second line of its report.
If you are "noticing" this problem somewhere else, please post a followup that describes what you are seeing a bit more exactly.
