Please can anyone explain a surge in Console messages?

Question

I'm running OS 10.6.7, Safari 5.0.5 on an iMac, model identifier 9,1, Intel core duo, processing at 2.66 ghz.
Looking at my Console logs, I see a multitude of messages that look like this:
30/04/2011 13:06:34          [0x0-0x36036].com.apple.Safari[540]          Canceleld; 0; Empty 1
[The misspelling of 'cancelled' is pasted directly from the log.]
each group of repetitions is followed by this:
30/04/2011 13:06:34          [0x0-0x36036].com.apple.Safari[540]          *** process 540 exceeded 500 log message per second limit  -  remaining messages this second discarded ***
The most recent changes made prior to this epidemic were as follows:
A few days ago, in order to stop endless "attempt to pop an unknown autorelease pool" messages about Western Digital Drivemanager, I got rid of the WD drive manager, but continue to use a Passport external drive for Time Machine without any obvious problems
A few days before that, I upgraded from Safari 5.0.4 to 5.0.5
I'd be interested to hear if anyone is has seen similar behaviour, which makes it hard to read other Console messages, and very grateful to hear any suggestions or solutions.

Looks like the problem stems from that update. I'd post here where the Safari people may be more able to help you. You want to take care of this not only because it's making it difficult to read in Console, but because these errors will eat up your drive space.
