Hi Team,

i am working on gatling 3.5.1 setup in my machine and trying to hit some backend endpoints and with the following configuration.

users: 300
ramp:5m
duration:10m
think:20 sec

getting the following error in high count and did a comparison of error rates of gating to the APM where i am seeing only some timeout over there…

j.n.c.ClosedChannelException 828
N/A j.i.IOException: Premature close 25

Hi,

First, Gatling 3.5.1 is old. You should upgrade to 3.7.6.

Then, those errors mean the server has closed the socket before sending the response, which could be the result of your server side timeout.
