[karate 1.4.1] OOM when load testing with mock for several minutes #2530
Comments

@brown-kaew I'm considering this low priority because it never has been reported by anyone else. also 1.5.0.RC3 is what we consider the latest available version. thanks a lot for the research, it would be great if you can also suggest a fix and perhaps contribute a PR |
