Console stops showing new All Messages

Question

On 1/28 I noticed that the All Messages report from the Console utility was not reporting any messages newer than roughly 11:30 PM on 1/27.
Logging in to my Admin account and viewing the "system.log" file (in Console) showed that messages were still being sent to that log. The last message reported by All Messages was a system sleep message at around 11:30 PM on 1/27. The first messages not shown by All Messages (but actually present in the system.log file) were at the system wake event around 1:30 AM on 1/28, during which the syslogd process crashed with a bus error. The rest of the system log filed showed all the expected messages up to the present and no unexpected messages. I have no history of prior crashes of syslogd.
Booting in Safe Mode, resetting PRAM, verifying the disk, and repairing disk permissions all had no effect. Messages were still going to system.log (viewable only by an admin Account) but were not reported in the All Messages display in Console (even for an Admin account).
At midnight on 1/29 the system rolled over the system.log to a new file and, automagically, new messages once again appeared in the All Messages report. There were no other messages in system.log indicating any other recovery action happening except for the log rolling over.
The Console reports are now working fine again, but I've lost a day in the All Messages report.
Since things are working again for me, this is not really a question. Take it as a point of information for anyone else experiencing a similar problem.
Possibly related to this, I've noticed that since the 10.5.6 update the Console All Messages report periodically displays the last message multiple times. These repeats have the same time stamp so they are not actually new messages, and if you click the Reload button on the Console window all the duplicates vanish leaving only the correct, original messages.

Thanks for that.
I did not spot any messages in system.log related to aslmanager. I should also point out that I have NOT experienced the problem reported by some others where aslmanager runs wild and chews up a lot of CPU time.
In fact while puzzling over this for the past day I watched Activity Monitor closely and never once saw aslmanager appear despite multiple reboots.
I did look in the daily asl log files and found the file for 1/28 was empty.
Again, all of this is just points of info for others who might be dealing with a similar problem.
