Hi Stephane/ Team,  
I updated my gatling version from 3.0.0 to 3.7.4. When did a performance test with 3.7.4 we noticed 15% of failures with the below errors. We are not seeing the same with 3.0.0 version. Kindly help us understand.

j.n.c.ClosedChannelException  
j.i.IOException: Premature close

If you can’t share remote access to your application, either publicly or privately (through a consulting contract under NDA), nor build a sample app that exhibits the same issue, I’m afraid there’s nothing we can do.
