This is a server error and should be resolved by your host

Leolam -

I saw your answer and would appreciate a bit more detail as I'm having the same problem - sitewide for a site that worked fine on a test server (running Joomla 3.75) then was overwhelmed when moved to another. In both cases, the site is on a Siteground VPS and Siteground support keeps telling me the problem seems to be caused by notifications on the site spawning enough processes to throw 503 errors.

There are about 100-200 users online at any given time (and many more trying to register which also is probably a bottleneck). The VPS has 10 core, 12gig RAM and the stats show that nore more than 50% of each are being used.

How best can I troubleshoot this? Thank you.
