@Tom-Elliott When I restart the server, it works again, but then the error happens again

[wanderson]

@Tom-Elliott Would not the httpd be down?

[Tom Elliott]

What? Why would httpd be down?

This sounds like a max_connections issue to me though.

[wanderson]

@Tom-Elliott Yes, after a few minutes, give the error http 500

[wanderson]

@Tom-Elliott

I will try to apply this rule in apache

<IfModule mpm_prefork_module>
	StartServers          4
	MinSpareServers       20
	MaxSpareServers      40
	MaxClients           200
	MaxRequestsPerChild  4500
</IfModule>```

@wanderson Is it giving 500, or is it getting “connection” errors? 500 means apache is responding.

[wanderson]

@Tom-Elliott, yes, Was giving HTTP 500 connection errors while doing the image upload task

[wanderson]

Problems began to appear after I started adding more than 20 nodes, I’m currently using 34 fog nodes

@wanderson Maybe too many clients hitting the apache with requests? Please check your apache access and maybe error log to see what’s going on and how many requests from which hosts are coming in.

solved: update mysql.user set plugin=‘mysql_native_password’;
