DBG/400 Latest News

RAM upgrade on the host server, bringing the host up to 8GB and this vm to 3.6GB. As the vm is still a 32bit Debian Lenny install it's not able to use memory beyond that. No recurrence of the page allocation failures since moving to the Realtek NIC so far. Before switching NICs the error cropped up within a day on 2.6.31, so I'm hopeful it's sorted.

Still more struggles with the server. It managed a week without the allocation errors, running on a 2.6.28 kernel, until I had a large amount of files to move from my desktop to the server over the gigabit link. The error happened again at the start of the transfer. After a reboot into the latest kernel I can trigger the error most times I do transfers, but it happens at other times too. I've now put in a Realtek gigabit card and will see how it goes with that. The errors don't seem to do much beyond expanding the log files, but that doesn't make them any less annoying.

Foswiki 1.0.9 is now available. This server has been running the release candidate (1.0.9rc2) for the last week and it's worked well.

I've updated the firmware on my router to the latest version of Jonathan Zarate's Tomato firmware plus Rodney Chua's SpeedMod patches. That seems to squeeze out the best performance from my Linksys WRT54GL:

VirtualBox is at 3.1.2 but I just cannot get a stable host system with the 2.6.31* Karmic kernels. I also think setting the network adapter to use the virtual Intel PRO/1000 device causes instability too. There are no problems with a 2.6.31 kernel and VirtualBox on my backup server. That may be down to it being a 32bit host install - this is on a 64bit Athlon II machine - but I still can't pin down a cause.

Still getting the occasional page allocation error even with the old kernel from Jaunty. Updated VirtualBox to 3.1.0 without any improvement, so trying again with 3.1.2.
