grep out of memory error

[Dragos Ionita]

Hi,

not sure that I'm in the right mailing list here, but I got myselft  
the 6.1-RC1 amd64 iso yesterday and installed it.

I've got a minimum system running and just 10 minutes ago, I ran a  
'grep' command and it returned an "out of memory" error.

The command run was:

grep -d recurse sasl /*

The error caused:

swap_pager: out of swap space
swap_pager_getswapspace(16): failed
HOSTNAME kernel: pid 618 (grep), uid 0, was killed: out of swap space
Killed

Not sure, but this seems a bit odd; I've got one GB of RAM and 512M  
of swap space allocated.

Running top beside the command gives you a nice view of what's  
happening: All of the RAM is used up almost instantly and the the  
swap space. All in all, in about 3 seconds, I get that out of memory  
error.

Again, I'm not an expert in these matters, but it seems odd that grep  
needs more than 1.5GB to grep (even if it's recursive from the root  
dir).

Does anyone else experience that problem as well?

Thanks,

Dragos
