You're right that I had an outdated BIOS, which I've now updated, but upon further review I don't think that is/was the culprit. I've since had the issue re-surface and this time I noticed many lines like this in the dmesg (not sure how I missed it before):
WARNING: mclpools limit reached; increase kern.maxclusters So I've upped kern.maxclusters to 8192, however, I'm not sure if I really should need to. This machine is a firewall/router for my home network running a few services (sshd, named, httpd, tomcat) for about 5 users. There's also a machine that is running Transmission BitTorrent client behind the firewall, maybe that could be the culprit? -Nick On Fri, Dec 2, 2011 at 9:29 AM, Erling Westenvik <erling.westen...@gmail.com> wrote: > You should try upgrading BIOS.
