I did also before have similar CPU issues on the server. But this one has already been fixed. And later I did have some other problem by inserting, editing, and publishing new articles to the blogs. Normally after the insertion, editing, or publishing the page will be automatically loaded. But instead i had a white page. I wonder what will be the reason for this. Suddenly i saw this blog page ?? and Otto42 just give me a good solution of reducing the CPU issues and accidentally solved the problem with white page also. Because all the do_pings schedules are still in the database.
Thanks Otto42.
