Hi, I am trying to do some load testing of Apache 2.4 on Redhat. Configuration displayed when I run "httpd -V" shows: Server MPM: prefork threaded: no forked: yes (variable process count) I am using Jmeter to test, and when I increase the number of simultaneous threads to > 200, I am seeing increasing number of errors, with a lot of "connection refused" errors, e.g.: org.apache.http.conn.HttpHostConnectException: Connection to http://10.0.3.10:80 refused at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:190) at org.apache.http.impl.conn.ManagedClientConnectionImpl.open(ManagedClientConnectionImpl.java:294) at org.apache.jmeter.protocol.http.sampler.MeasuringConnectionManager$MeasuredConnection.open(MeasuringConnectionManager.java:107) at org.apache.http.impl.client.DefaultRequestDirector.tryConnect(DefaultRequestDirector.java:643) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:479) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:906) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:805) at org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl.executeRequest(HTTPHC4Impl.java:517) at org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl.sample(HTTPHC4Impl.java:331) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerProxy.sample(HTTPSamplerProxy.java:74) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1146) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1135) at org.apache.jmeter.threads.JMeterThread.process_sampler(JMeterThread.java:434) at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:261) at java.lang.Thread.run(Unknown Source) Caused by: java.net.ConnectException: Connection timed out: connect at java.net.DualStackPlainSocketImpl.waitForConnect(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(Unknown Source) at java.net.AbstractPlainSocketImpl.doConnect(Unknown Source) at java.net.AbstractPlainSocketImpl.connectToAddress(Unknown Source) at java.net.AbstractPlainSocketImpl.connect(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at org.apache.http.conn.scheme.PlainSocketFactory.connectSocket(PlainSocketFactory.java:127) at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:180) ... 14 more I've been trying to re-configure the Apache to avoid these errors, e.g., increasing "MaxClients", and I've also increased the amount of memory for the machine (to 4GB) but so far, nothing I have done has improved the situation. Is there something else that I can do to try to get the Apache so that it can accept the larger number of connections?
