The vegeta benchmark triggers a crash in the code that handles Lua scripts #25

Closed SDpower closed 5 years ago

SDpower commented 5 years ago

I try to use https://github.com/tsenart/vegeta do benchmark... it will really easy crash just 500 clients.

echo "GET http://127.0.0.1:3000/counter/" | vegeta attack -rate=500 -duration=30s | tee results.bin | vegeta report

The logs:

-> % ./welcome.sh
Try editing the markdown file in samples/welcome and see the
results instantly in the browser at http://localhost:3000/
