Prevent 502's for all sites when changing configs

[KarelB]

I have a Plesk 12 server running that works great. But the problem is that whenever one of my shared hosting customers changes something out a domain or subdomain, all the other sites on the server give a 502 error.
The reason why is clear to me: apache is reloading its config while nginx is still active, but sees apache as being down and therefor throws a 502 error.

Is there any way to prevent this from happening? Because it's happening a lot and people are sending in 'site down' reports while there's actually nothign wrong with the server or their site.

I tried searching for "502" on the forum, but it seems that keywords is too short to be used for a search...

You can try to use graceful Apache restart - http://kb.odin.com/en/112020
