Hi, I am using tomcat 7.0.25 on linux and java 6u30 to perform some load
testing, and came to this observation.
Performing some ab (apache benchmark) tests as specified in [1] and the http
connector configured as:
- references to an executor as
<Executor name="tomcatThreadPool" namePrefix="catalina-exec-"
maxThreads="150" minSpareThreads="4"/>
- without an executor and with a minSpareThreads="15" in the connector
- no minSpareThreads at connector and references to executor
After 60s of the ab test, I see all request processor threads are terminated
(reported by jstack PID or ps -p PID -o nlwp). But accordingly to the
connector documentation "The minimum number of threads always kept running."
Is the connector docs wrong or is it a bug in the connector threading
implementation ?
<Connector port="8080" protocol="HTTP/1.1" minSpareThreads="15"
connectionTimeout="20000" processorCache="150"
redirectPort="8443" maxThreads="1024"/>
1. ab -n 50000 -c 1000
'http://localhost:8080/examples/servlets/servlet/SessionExample?dataname=foo&datavalue=bar'
