-----------------------------------------

             Summary: GC Overhead limit exceeded error during running a performance test on
simple Passthough Proxy
                 Key: SYNAPSE-1065
                 URL: https://issues.apache.org/jira/browse/SYNAPSE-1065
             Project: Synapse
          Issue Type: Bug
          Components: Proxy Services, Transports
    Affects Versions: 3.0
         Environment: ubuntu 16.04
4 core 8GB RAM
            Reporter: Chanaka Fernando
            Assignee: Hiranya Jayathilaka
            Priority: Critical


I have a simple Passthrough Proxy and a back end service which is written in netty and simply
echo back the request message. When I run a performance test using Jmeter (with 100 concurrency),
I am getting the following errors in the synapse log file and console.
