Multiple jersey-clients with clashing responses from Single tomcat server
I have a single tomcat server running on port localhost:8080 When I run multiple threads/request against the server, every once in a while the responses to those requests clash. What I mean is that if Alice and Bob send out requests, Alice might get the response belonging to Bob and vice versa. Also, every once in a while Alice and Bob might both get Alice's request. See example below. Note: this only happens like 3% of the time, but 3% out of 2000+ requests is a lot of failures.
- Alice -> sendRequest1
- Bob -> sendRequest2
- Alice -> receiveResponse2
- Bob -> receiveResponse1
My question is, Why does this happen and Is there a way around it?
Perhaps there is something in the configuration I am missing.
Here is some more info so that I can cover the basic questions. I am using the Jersey api client to talk to the server (com.sun.jersey.api.client.WebResource) which is supposedly thread safe (at least thats what it claims)
This is NOT a threading problem. 1) I have verified that each thread has its own instance of the client. 2) I ran multiple processes (all single threaded) at the same time and found the same results.
I ran them with one thread on the server side and the clashing still happened.
Here is my catalina configuration (in the server.xml file)
<Connector port="8080" protocol="HTTP/1.1"
maxThreads="10" minSpareThreads="0" maxSpareThreads="5"
From what I understand about HTTP, a new port is opened (or reused) on each request. The server is then supposed to send the response the the exact port the request came from. If this is the case, then no clashing should happen.
