I am not seeing any problems related to this other than pages of errors in messages. I see them in bursts of 10 to 177 with about a dozen being most typical. The process with PID 5 (assuming that this is what "pid5" means) is pagedaemon. This looks like it might be significant. Can these be ignored? And, if so, can the messages be silenced? I hate meaningless errors messages that might distract from something more important. I will be updating to the most recent 10-STABLE in a few minutes (to get security patches), so maybe they will go away.
