Thanks for help Moinak! I will send the info to you tonight when I sit with my KDE4 builds again.

ZFS ARC cache can be the culprit but seems unlikely that ARC will grow too much beyond 1GB. Can you provide the following information: Execute prstat when the build is halfway through, take a screenshot and send it to me (not to the list :) ) After the build has completed, as root user execute echo "::memstat" | mdb -k and let me know the output. I had been using my home desktop for about 1yr to do huge amount of builds and ZFS would cause swapping trouble since I had only 1GB RAM earlier but it never caused problems. The system now runs like a rocket after I upgraded to 4GB faster RAM. I can play games with a build running in the background. I used to run heavy duty ON and BeleniX LiveCD builds longer back on the Acer Ferrari, 2GB RAM, sloooow harddisk without problems when I did not have a desktop.
