gitlab-http-router `Reached heap limit` error when running tests against GDK

The GDK tests are now running the http-router enabled. We encountered an issue where the http-router seemed to stop due to a V8 fatal error.

These tests are running quite frequently and it has only been observed once. It doesn't seem to be related to the actual test.

The job is occurred in: https://gitlab.com/gitlab-org/gitlab/-/jobs/8121517248

This causes the test to fail with:

Errno::ECONNREFUSED:
            Failed to open TCP connection to gdk.test:3000 (Connection refused - connect(2) for "gdk.test" port 3000)
