@admin, i met the problem, is this normal,why?

Sometimes, i open my website, it shows:

This site/page has used all avaialble php / apache processes allowed on free hosting account.
Refreshing the page once the amount of apache / php processes are reduced will cause the site to work.
We would recommend upgrading your hosting account at IFastNet Premium hosting accounts , premium hosting accounts have MUCH higher resources dedicated to them.

If by “normal”, you mean whether it’s intentional, then yes, it is normal.

We don’t have an article specifically about this error message, but the article about Entry Processes is closely related. The article is written for people who exceed the daily limits, your issue is more about having a single usage spike.

Thank you.
