-----------------------------------------
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.
