INTERMITTENT NEWS AGGREGATOR?

My news aggregator seems to work somewhat intermittently. I visit sites that have new information. Having just gone through my news aggregator, I’m certain those sites were not listed there.
Is there some configuration problem? Is there a limit to the file size for an aggregator scan? If I’m subscribed to too many sites (approximately 100), will that limit what I get in my news aggregator?
