Over 800 per Day 'WebProcess' entries to All Messages Log?

Question

Yesterday, 8-5-13, I updated to OS 10.8.4 which included Safari 6.0.5.
At 4pm yesterday, the WebProcess entries into the All Messages Console Log began.
Today, 8-5, one day later, there are now 800+.
Is this normal?
Below are the entries that you see in the log.
Thank in advance.
(I monitor the All Messages Log as well as the System Log daily, so I know the catalyst was the updates )

I think I just got lucky!
I emptied all the USB ports and the FW from the back, then did a Safeboot then a restart.
From the looks of the log now, it has straightened out.
Just for the record, I had a WesternDigital MyBook in a USB port,
A USB licenser dongle for Cubase7,
And a belkin USB to an audio/video editor,
lastly, a Firewire to the DAW's mixing console.
After removing all of those then the SafeBoot procedure, I get the pic above.
Tomorrow, one at a time, I'll reconnect in the order of need, the FW/USB ports, recording the results.
Now I'm thinking that it's probably incomptibility with one of those connected.
