poky consume all memory on redhat-based linux in virtualbox

Hi all,
         When I tried to build image on Fedora and Scientific , I encountered same problem that poky consume all memory and then system became very slow. The poky process also moved on hardly. After killing poky process, memory wasn’t freed. I had noticed that some process like “cc1”  brought up by poky process were still alive. Anybody know what’s the problem?
         Another trouble, toolchain built on Ubuntu can’t work well on Fedora. Qemu fail to mount nfs , but it can work on Ubuntu.

Best regards
Feye

How much memory do you have? I've seen the build process peak at  
something like 2.5GB. I started running with a VM that only had 1GB  
allocated and had the same problem as this caused lots of swap file  
activity. It was mainly the compiler/linker that was using most of the  
memory, which would explain why you see 'cc1'. Don't forget that the  
build process fires off multiple processes.

Hi Chris,
         The VM has 1GB memory. Normally 400-500MB is consumed on Ubuntu ,so I think it is enough. Does redhat-based linux need more memory?
         Because I had closed terminal running poky, all process of poky should quit.
