It means that one of your iterations didn’t have time to finish before k6 forcefully terminated it. The reasons for that could have been many:
- your test or scenario duration ran out after that iteration had started, and the iteration didn’t finish running in the
gracefulStop(30s by default) time k6 leaves for iterations to finish execution - you had a
ramping-vusscenario and were ramping down VUs and an iteration didn’t finish in thegracefulRampDownperiod - you hit Ctrl+C
- you had a threshold with
abortOnFailenabled - you called
test.abort()from thek6/executionmodule - (there are probably other potential causes for this that I am forgetting)
In any case, the fact that 1 out of your 1047153 script iterations didn’t fully finish running is probably not a big deal
