No memory when copying files

I am using default ARCH kernel (2.6.31.6-1) with reiser4 and TuxOnIce patches, laptop with Core2 Duo P8400 and 3Gig of RAM. The ploblem is that when i copying rather big files (with rsync or dd) or even burn iso with K3B system memory is dramatically decreased.

$ free -m
             total       used       free     shared    buffers     cached
Mem:          3015       2985         29          0         41       1916
-/+ buffers/cache:       1027       1987

The system began using swap and become very unresponsive. The using of Virtualbox is not comfortable. When copying is complete system return to it normal state.
How to solve that?

Re: No memory when copying files

At the console you could try to use nice for the processes. But I'm surprised that your system started to use swap space where there is still 2G of free memory around. It should have kicked things out of the cache instead.
