    Hello Awadesh kumar

    I hope you’re well today!

    Our sys-admins checked the server and it seems that site’s causing the PHP processes number limit to be hit. Every know and than it causes maximum number of 25 children processes to be hit and that slows down performance.

    In general, the problem is that whenever site is loaded or some background task is fired up (e.g. by WP Cron or some plugin running on site), there are some PHP processes executed on the server. There’s a limit on that, in order to maintain server performance. If the site’s triggering to many of these processes, the issue happens.

    The reason for this is usually either a high traffic or a lot of parallel requests (like lot of scripts being executed) or some slow scripts running. Or a combination of them.

    I can see that the site doesn’t seem to be getting much traffic though there seems to be a big number of page loads for each visit so that might actually mean e.g. various indexing bots hitting the site (server-side stats don’t filter them out) but still – “load is load” and it’s firing PHP scripts on site.

    I took a look at the site configuration and it doesn’t seem to be especially complex but there is “something” resulting in that. I actually suspect it might be a Live Chat plugin (unless you got some additional custom code on site that’s doing some tasks in background, that I don’t know of) and I think it would be a good test to temporarily disable it for some time (few hours at least) and see if that helps with the site.

    If yes, then there’s a chance that replacing it with some other solution might help but if the site’s still behaving that way even without Live Chat plugin active and/or replacement is not possible – switching to a higher plan would be a reasonable solution in order to provide the site with more server resources.

    Kind regards,

    Adam
