I figured it was a bug. Unless anyone has any other information to the contrary,
I'm going to file a bug report today.
Seeing the Ajp package is deprecated, are the Warp connectors fairly stable?
The documentation for the Warp connectors is weak (FIXME's) and incomplete
when compared to the Ajp documentation.

either way, I believe the org.apache.ajp package is deprecated.

Subject: Error? org/apache/ajp/tomcat4/Ajp13Connector createProcessor()
Greetings,
We were noticing some 'No processor available' exceptions
associated with the Ajp13Connectors under heavy load.
I downloaded the Tomcat 4.0.6 connectors source and had
a look at the code responsible for creating a new processor to
handle an incoming Ajp13 socket connection from Apache.
In org.apache.ajp.tomcat4.Ajp13Connector.java, in the
createProcessor() method, I noticed that there was no logic
to handle the case if maxProcessors was configured to "-1"
for infinite processors. In the HttpConnector source, if
maxProcessors was "-1", then it returned a newProcessor().
I modified this createProcessor() method to function in the
same manner and the Ajp13 "No processor available"
exceptions disappeared.
private Ajp13Processor createProcessor() {
synchronized (processors) {
if (processors.size() > 0)
return ((Ajp13Processor) processors.pop());
if ((maxProcessors > 0) && (curProcessors < maxProcessors))
return (newProcessor());
else {
if ((maxProcessors < 0)) // my new code returns a new processor
return (newProcessor()); // if maxProcessors is "-1", aka infinite.
else return (null); // original else return result
}
}
}
My question then, is this a bug in the Ajp13Connector functionality?
Or is there some design reason to not allow the user to configure
the Ajp13Connector for infinite processors via the "-1" option.
I couldn't locate any documentation that says Ajp13 connectors
cannot and should not be configured for infinite processors.
Thanks,
Eric Scroger
