This situation indicates that the PHP processes on your website are taking too long to close, causing all available slots to be utilized. Once the maximum number of slots is reached, the website becomes unable to load or open any additional PHP connections or website queries until one of the existing PHP connections is closed. Consequently, MySQL connections are also affected, as no further connections can be established. This explains why you are encountering this error on your website.
We recommend contacting your web developer and providing them with the above information. They should ensure that your website is optimized to prevent long-running database queries from exhausting the available connection slots in the future. Additionally, they should ensure that queries are terminated promptly after completion. Taking these measures will help resolve the issue at hand.
