How to free up memory on 256mb model?

[jarrodr]

Hi guys,

Need some help, I seem to be having a memory problem. How do I identify and free up memory up? - Any tips and tricks.

I have TightVNC, SABnzbd, Sickbeard, Deluged and Samba installed. I have a 4gig SD card.

All help is much appreciated.

Memory ? Or Disk Space ?
If you mean Disk Space, then run this as root from /

Code: Select all

du -hx --max-depth=1

If you mean memory, check top and see what process is using up most of your memory

Memory as in RAM. Sorry SirLagz, I'm a noob to Linux.
How do I check the what processes are running?

"top" shows me current memory usage. How do I free memory? eg. Killing processes.

In general, its very dangerous to kill processes in Linux - there may be unintended consequences.

Although, if a process is just sitting there, it wont be using much RAM - it will all be swapped out - if you have a swap disk enabled.

Look up swap disks, and the 'kill' command
