OK, this morning I had the time to SSH into my phone and understand how the osso-rss-reader works. Just found out the app was getting nuts when processing the cache.

I completely removed my cache:

Nokia-N900-42-11:/home/user/.osso_rss_feed_reader# rm -rf cache/*

And everything just works again, RSS app as well as the RSS widget.

Everything is running again and load average is below 0.5:

Nokia-N900-42-11:/home/user/.osso_rss_feed_reader# uptime
11:12:17 up 2 days, 10:35, load average: 0.15, 0.44, 0.33

So, for future references, if you RSS reader goes crazy, start by removing its cache.

BTW I had around 90 RSS feeds in place. Removed some, before deciding to remove the cache. I had some thoughts on which RSS could be leading to problems, so I had to remove 'em. Didnt fix untill I cleared the cache, anyway...

If you still have problems after removing the cache/ contents you may try to edit /home/user/.osso_rss_feed_reader/feedlist.opml and remove some feeds, which may also cause high load.

A feed entry is within the <outline> tag, for example:

<outline text="Historico FUG-BR" title="Historico FUG-BR" description="Historico FUG-BR" type="rss" htmlUrl="http://www.fug.com.br/historico/html/freebsd/" xmlUrl="http://www.fug.com.br/fug_hist_rss.xml" updateInterval="-1" id="jileean" lastPollTime="1277993344" sortColumn="time"/>

Thats it.

Thanks again.
