Shared and Reseller accounts are limited to 25 simultaneous processes. VPS have no processes limit. Note: Most sites will work perfectly with a 25 concurrent processes limit. Processes open and close so quickly that they hardly ever overlap. If you are exceeding the limit, you either have too much traffic for a shared server, or you need to optimize your database (for faster queries).
