Two presented messages regarding ad_context_bar or something. I thought I would have found it in the log. Restarting AOLServer manually after the kernel upgrade allowed it to restart properly at which point I was able to upgrade the rest of the packages.
Other than that, the upgrades went smoothly. One comment from a client was that the site appeared to be slightly faster.
I must say, congratulations! Since I started using OpenACS, it has improved considerably and just keeps getting better. Great work everyone!
