I googled it and most of the results show your post here and the one I assume is you on the linksys/cisco pages. I find it disturbing that no one there has even attempted to reply to you.
The only other reference I saw to that line was to something called OpenS/wan. Their issue seemed to be related to running out of RAM. At least, that's what they were assuming. No one ever posted a definite answer to any of the threads.
I usually have had pretty good experiences with Linksys support. It really changes my mind about them to see this. Especially when I was intending on upgrading to this exact router when I finally get everything switched over from 10/100.
