I build blog with Paid Membership Pro plugin, and on production hosting it works fine but on live hosting where domain is parked I got a few times a day 503, 507 or 508 error. I write with support and they see nothing wrong, but on Webmetrics you can see that call to wp-index.php and admin-ajax.php is something what eat massive of resources sometimes.
[https://bezpieczenstwoistrategia.com])If someone could take a look and tell me what is wrong, or maybe I should just change host providers, on perhaps Site Group (now is Hostwinds)? Pls help! 😉
EDIT:
* CPU resources limit was reached for your site
* Physical memory resources limit was reached for your site
* You have reached the entry processes (the number of simultaneously running php and cgi scripts, as well as cron jobs and shell sessions) limit 462 times
* I/O usage resources limit was reached for your site
I see this when I check Resource Usage, and… the thing is this host offers Unlimited Bandwith, Unlimited Disk Space, etc… I don’t get it.

Move to a VPS provider such as Linode, Vultr or Digital Ocean and get a solution with at least 2G of ram.
Yeah your resources are definitely being exhausted. The first step is to see if you can increase the limit of your resources. Unlimited bandwith and disk space are separate from cpu and memory usage. Your processes seem a little high though
Your site is a fat whore resource hog. The 400+ crons added with normal http requests is over-loading your server. Throwing more servers on top doesn’t get to the root of the issue. What efforts have been put in place to optimize, cache and limit cron usage?
Have you run a malware scan? I’ll often get new client sites doing this when they’ve been hacked.
