The files are being renamed and created, but all of my messages are still being written in /var/log/messages.2, with /var/log/messages and /var/log/messages.1 being completely empty. It would appear that while the cron rotation is functioning, sysklogd is not switching files. This is after about two and half weeks of the Netfarm being up.
seems to work fine with a snapshot version from the last weekend, so if anything was broken, this should be fixed already.
