Hi,
When we ran a stress test on our application, it hang Tomcat service. We found an INFO
message in stderr a message below
INFO: All threads are busy, waiting. Please increase maxThreads or check the servlet
status200 200
I have tried to increase the maxProcessors in \conf\server.xml from 200 to 500 and 500
to 1000, but that didn't help. We ran a stress test with 200 concurrent users. Here's
our sample setting for 500 max processor
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector" acceptCount="10"
bufferSize="2048" connectionTimeout="20000" debug="0" enableLookups="true"
maxProcessors="500" minProcessors="5" port="8080"
protocolHandlerClassName="org.apache.coyote.http11.Http11Protocol" proxyPort="0"
redirectPort="8443" scheme="https" secure="true" tcpNoDelay="true"
useURIValidationHack="false">
<Factory className="org.apache.catalina.net.DefaultServerSocketFactory"/>
</Connector>
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector" acceptCount="10"
bufferSize="2048" connectionTimeout="20000" debug="0" enableLookups="true"
maxProcessors="500" minProcessors="5" port="8009"
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler" proxyPort="0"
redirectPort="8443" scheme="https" secure="true" tcpNoDelay="true"
useURIValidationHack="false">
<Factory className="org.apache.catalina.net.DefaultServerSocketFactory"/>
</Connector>
How do we solve/increase the maxThreads issue?
Thanks,
Tuan
