Steps to reproduce

first you need to change https://github.com/koisose/qwik-error-build/blob/main/src/utils/bullmq/config.ts to your own redis instance config you can use upstash

then if you want to see the error run pnpm run build it will hang like this:

It would be great if we could get a minimal repro of this. It doesn't need to be a working app, just the minimal source that causes the optimizer to hang.

yes sir heres the repro link https://github.com/koisose/qwik-error-build just run:

pnpm i
pnpm run build

and i also include the fix here https://github.com/koisose/qwik-error-build/blob/main/src/utils/bullmq/queue-fix.ts this is not optimal i know but it is enough for my use case

I accidentally stumbled upon an issue. I was developing with Ubuntu v20, and everything was working fine. However, when I switched to Ubuntu 22.04, the server build process would not end execution. I couldn't figure out the problem, but it seems that the Qwik server build process executes the code at the build time to create necessary pages. During execution, it tries to resolve dependencies, but, weirdly, it can't resolve ioredis and bullmq. Although, if the build.server command exits at the end, there is no problem running the application.

But in the end, this happens only when the ssg flag is not disabled on the server adapter. If it is null, since the server build is not trying to create static pages, there is no hanging.
