Installing Plugins Stalls

I have created a Favorite Plugin Group called Managed which contains 4 Plugins.
When attempting to install to 37 sites in the group, it inadvertently stalls somewhere in the process. Sometimes early on sometimes later in the process.

Is there a setting I can tweak to enable this process to complete? Or, perhaps a better way to organize it so that it end goal is accomplished more effectively?

Hi @aboveallmedia,

I reviewed the System Report and your server config seems good.

When you attempt to install plugins, and when it stalls, can you please open your browser console and see if there are some errors reported?

To me, it looks like the server hits some limit after some time and it probably kills the admin-ajax.php script execution.

Also, have you tried to measure time to see if there is some pattern like it always stalls after 60 seconds?

Hi Bogdan

I opened the console as you suggested. Halfway thru it stalled and there were some odd errors stating that my network information had changed. I have been having to reload my browsers this week for some reason. But it is not happening today. I was able to deploy today. I am assuming this caused session errors resulting in the stall.

Perhaps ISP is having intermittent issues and I caught it at the correct time today is why it worked today.

Thank you for suggesting to check the console. I should have thought of that. LOL.

I’ll keep an eye on it.



Hi Basil,

thanks for letting us know. Let us know how it goes and if any further help is needed.
