Got FreeBSD 9.0 64 bit, with the configuration you are talking with 4 cores (under VirtualBox)... Can't reproduce it even under high loads. Ok, I think I'll need a program that reproduces the problem, if you want to send it to me privately it is ok. Also few additional points: - what is your config.js file? - what locale do you use?
