You don't provide enough information to be able to figure out your issue.

Possible issues:

  • you're using an eager feeder (large CSV like feeders are lazy in modern Gatling version, but no idea which Gatling version or which kind of feeder you use).
  • your system under load or your bandwidth can't handle the load you're trying to generate and your virtual users pile up in memory (can't complete their journey and no virtual users keep on arriving).
