Drupal feeds module causing high cpu usage when pulling feeds

Question

I am using the Drupal Feeds module to download the feeds from an external site. I have setup a dedicated content type to pull the feeds and then created nodes of another content type for the individual feed items.

After updating the site recently I noticed that the site was using the CPU continuously so much so that the hosting tech support notified me about it.

I proceeded to limit the frequency with which the feeds were being pulled but the CPU usage remained constant and I was finally forced to disable cron.php.

This never happened before the update.

Checking the dblog I noticed that the JobScheduler initiated the feed pull (I had set the watchdog to print the title of each node being created) and was repeating this scenario every minute 24x7.

I have not figured out what is causing this issue or from where to start?

Any possible solutions guys?

Site runs on Drupal 6.

If you are in shared hosting, then it is the right time to upgrade to VPS or Dedicated Server.

I had a same issue How to control resource usage of my website? , better you can remove the unwanted bots. You need to see the Access Log in your hosting control panel.

try disabling your modules one at a time to decide when the load time gets really high and remove the unwanted modules and also it delete from modules folder.
