Solved App unresponsive due to error

[imc67]

One of my WP Dev apps is “crashing” regularly and this is the error message:

server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting

How can I increase this setting?

It may be due to a hacking attempt

@privsec thanks for finding however the xmlrpc on my sites are always locked for security reasons.

However, after searching around the internet and this forum I combined some answers and tried the following:

In the filemanager there is a folder /apache/ and it contains a file mpm_prefork.conf.

There I changed the (very low values) to:

StartServers	10

MinSpareServers	10

MaxSpareServers 40

MaxRequestWorkers	  256

MaxConnectionsPerChild   1000

Let’s wait and see if this solves the issue.

@imc67 how much daily traffic do you get?

@imc67 do you have any plugin installed which may use websockets? Those are long-lived, so each websocket connection will use one request worker.

mpm_prefork.conf

Indeed, fixing the values in that file is the correct fix.

I checked the inspector but couldn't find any

The changed values result finally in a more stable situation.

This is not a high traffic site (5k month) and the only one created with Avada Theme and that's really a "monster".
