Hello Peter,

I run with 3 threads concurrently and apply Smart close with filter sample.jmx, However, I am running into the issue that the after thread 1 and 2 finishes, thread 3 face Response message:WebSocket I/O error: Socket is closed. How can I bypass this issue?

I have no idea why your server is closing the connection (and i’m wondering why you are asking me ).

If I disable the close connection, the threads do not face issue. DO you have any idea?

No. JMeter threads are independent, i cannot see how an action on one affects another.

The best thing to do is to make a WireShark capture, so we can really see what’s going on network level.
