If you could send the httperf output, that might provide some insights into what is going on.
Also, I would use tcpdump to collect a packet trace from an experiment, and then look through the trace to determine if the client is trying to reuse a connection that the server has tried to close (in which case the server will issue a RST), or if something is going wrong on the server side and it is terminating the connection with a RST without the client having done anything wrong.

Subject: [httperf] How to solve connreset?
Thank you very much for replying to solve fd-unavail.
Now, I'd like to solve connreset error but I have no Idiea to solve that.
In the test I just try rate = 3 for 4 minutes, the result has only 6142 connreset errors.
I use 1 client and 1 web server. there are linux. The Client generates requests to a java servlet application (using apache tomcat) that performs a CPU-intensive job (calculate the matrix).
I read some messages before about netstat detail but I still have no idea.
The differnce of 'netstat -s' before and after test
TCP: 0 failed connection attempts
13 connection resets received
40 connections established
4055 resets sent
Have any idea to solve this error?
