I use Chicken-of-the-VNC on Mac into my OpenSolaris server regularly. I found that I had problems similar to yours at one point. It also started behaving strangely (things like ignoring keyboard input once the screen-saver kicked in).
After I stopped the vnc server, deleted the .vnc directory and re-started the vncserver, it's been rock solid. BTW, I get the RANDR messages too, but it doesn't seem to be a problem. Gary -- This message posted from opensolaris.org
