Timeout when executing rake db:migrate

Product Support Self-hosting

AI-generated summary

andreaswittig reports intermittent timeouts during rake db:migrate, specifically a MiniRacer::ScriptTerminatedError, suspecting a JavaScript execution timeout. pfaffman asks if it’s running on a Raspberry Pi, which andreaswittig denies — it’s a VM with 1 vCPU, 1 GB RAM, and 1 GB swap. merefield questions why rake db:migrate is being run on what appears to be a production install, noting it’s typically for development; andreaswittig clarifies it’s a test/dev machine. Ed_S references a previous thread where similar timeouts occurred due to heavy image processing, suggesting resource constraints or JS-heavy tasks may be the culprit. The issue appears tied to MiniRacer’s JS execution limits during migration, possibly exacerbated by low memory or heavy asset processing.

Every know and then I’m getting the following error when running rake db:migrate. Is it possible, that I’m running into a timeout here? If so, is there a way to increase the timeout?

rake aborted!
MiniRacer::ScriptTerminatedError: JavaScript was terminated (either by timeout or explicitly)

Any hints for debugging this issues welcome!

Is this a raspberry pi?

3

No, runs on a virtual machine with 1 vCPU and 1 GB memory + 1 GB swap.

4

If this is a production standard install, why are you running this rake job? It is only necessary in development (which is usually local). If it’s a cloud development server, then fair enough.

5

It’s a test/dev machine. Any ideas?

In this previous thread, the same kind of thing was a timeout: many images to be processed…
Job exception: JavaScript was terminated (either by timeout or explicitly)
