Hi--
Couple of things:
{610} begins and repeats 26 times so far....
First, the number in square brackets after the
SyndicationAgent string is nothing to worry about in this context. It's just the process ID of that program. So the fact that it goes up means nothing except that maybe periodically quits and relaunches (perhaps in sync with Safari).
Second, it looks like the log is giving at least a little hint to where you can look for the culprit feed:
<pre class="command">can't interpret: 'Fri 15 Dec 2006 21:04:10 -800'</pre>I'd look for a feed that originates on the west coast, and see if you can find one that updated or published at about that time.
It's been a long time since I wrote the RSS script I use on the site I manage, but I seem to remember something about the dates using the time zone name, not offset. Additionally, I think I had troubles until the dates were GMT dates, too. Here's the publication date and build date from my site's feed:
<pre class="command"><pubDate>Sat, 16 Dec 2006 22:45:01 GMT</pubDate>
<lastBuildDate>Sat, 16 Dec 2006 22:45:01 GMT</lastBuildDate></pre>See how it's "GMT" and not "-0000"? So you might be able to track it down that way...
