# X_JOB_CRASH_DIVERGED

## Means

a job run killed at a step boundary made an effect a different number of times than a clean run

## Typical cause

an effect — a row write, a mail, a call out, an enqueue — sits outside every step.run, so the retry after a crash makes it again

## Fix

`step.run('<name>', async () => …) around the printed effect, in the job crashProof named; then: x test job --filter <the test file>`
