I’ve cloned the same site over to another environment, this time running Apache, with similar PHP version, the issue goes away.
The PHP limits for exec and memory are identical, the Apache host probably has less resources. The main difference, the production server is running Litespeed as per previous comment.
@jason_hayes If you go to WordPress’s site health section and then the info tab, is the host running Apache or something else? I’m trying to rule out things atm.

Hi,

I have a number of sites all displaying the same issue, 5.4.2.

@ Sundar, Installed a clean version of 5.4.2, also the same issue.

Testing with images I’ve uploaded previously, I get the following message for images with a max long side of 2400.
“Post-processing of the image likely failed because the server is busy or does not have enough resources. Uploading a smaller image may help. Suggested maximum size is 2500 pixels.”
The image is 534kb in size.

It does upload, a refresh of the media library page shows the image.

According to cPanel, memory is fine however CPU usage is maxing out.

1 of the sites was put together around January time, I don’t recall the installed version at that time, the issue was not present.

PHP version 7.4.6 (Supports 64bit values)
PHP SAPI litespeed
PHP max input variables 1000
PHP time limit 120
PHP memory limit 512M
Max input time 120
Upload max filesize 12M
PHP post max size 12M

Imagick is also available.

Taking off the memory limit makes no difference. The error occurs long before the execution limits as well.

It’s returning 503 Server busy.

I’ve tried the edit option in the media library also, that just hangs without returning anything useful atm.

I’ve only just discovered this issue, and found this related thread so haven’t had chance to have a good dig around.
