Just took a look at the memory usage (with
free -m) on one of my Ubuntu servers and saw this:
total used free shared buffers cached Mem: 751 624 127 0 256 236 -/+ buffers/cache: 131 619 Swap: 299 0 299
- What is a buffer?
- If something needed RAM to process something, would a buffer give up its allotment (like cache would)?
- Is there any way I can find what's using the 256MB of memory for buffer?
- Should I be worried?
