[5.x]: "Generating Image Transform" Queue Constantly Running

[bryantwells]

Description

I am managing a site with ~100,000 image assets on a craft install.

Recently, I upgraded to Craft 5 and moved the transform process from AWS Lambda to the site's server. Ever since, the queue has been full of "Generating image transform" jobs.

Of course, I expect this after the initial migration, and the server gradually worked through a queue of ~500,000 jobs. But even after getting the queue down to 0, it is still regularly filling up with thousands of jobs (weeks later).

Moreover, the process stalls frequently, and I have to manually release jobs in order for it to continue.

The queue log is very opaque so this has been hard to debug. The only errors/warnings i am seeing have to do with reading .gif images, and are as follows:

2024-10-02 14:05:25 [queue.WARNING] [/home/ploi/patbates.com/vendor/pixelandtonic/imagine/src/Imagick/Imagine.php] Unable to open image /home/ploi/patbates.com/storage/runtime/assets/sources/321985.gif {"memory":8107552}
