Glad that it helped.

Just as suggestion, a machine running buildbot should run just the OS and buildbot; nothing else (if you have a windows machine probably the firewall and the antivirus are also suggested).

I run a master with 2 Gb and a slave with 4 Gb and rarely have memory problems; try to keep the system resource monitor up to see what is sucking memory and just close it (i bet is the web browser; it can eat easily a GB or 2).

If you are on mac or linux/unix you can check with ps aux to see what is going on with your system; 4 GB should be pretty much a good amount just for buildbot :)
