"Unable to start another process" message
In order to maintain the stability and performance of the servers, there is a limit on the maximum concurrent processes a hosting account can run. If a hosting account reaches its process limit and then tries to start a new process, the following message will be displayed on the website:
The page will reload automatically every 10 seconds in an attempt to start a new process.
To prevent such messages, you should optimize your applications and scripts so their execution time is reduced as much as possible.
