Platform: Intel PIII, debian testing/unstable (sarge)
Blackdown JDK 1.3.1 (j2sdk 1.3.1.0b-2),
tomcat4 4.1.16-1,
apache 1.3.26-1.1, apache-ssl 1.3.26+1.48-2
My problem is that when I do
/etc/init.d/tomcat4 start
there is nothing listening on port 8009.
Or rather: there is _sometimes_ nothing listening on port 8009.
When I have started and stopped tomcat and apache and apache-ssl, I
have sometimes been able to find something listening on port 8009. I
haven't changed anything in the configuration for this to happen.
Just started and stopped services. But the listening to port 8009
has gone away as mysteriously as it appeared.
I haven't found anything conclusive in the logs about this. There
seems to be stuff in /var/log/tomcat4/catalina.out related to Ajp13,
but I can't make sense of it (see log fragments below).
Has anyone else seen this, or similar behaviour?
I have used the commands
lsof | grep 8009
and
telnet localhost 8009
to determine if something is listening to port 8009.
Right now the first return no matches, and the latter prints out:
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
I have tried both the Coyote Ajp13 connector, with the following in
server.xml:
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
port="8009" minProcessors="5" maxProcessors="75"
enableLookups="true" acceptCount="10" debug="0"
connectionTimeout="20000" useURIValidationHack="false"
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>
And the old Ajp13 connector with the following config:
<Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
port="8009"
minProcessors="5"
maxProcessors="75"
acceptCount="10"
debug="0"
/>
But the behaviour is the same.
I have wondered if there is a problem with both apache and apache-ssl
accessing the same Ajp13 connector in tomcat. But I've stopped
apache-ssl a while back, and I still haven't seen any change in the
behaviour.
Thanx!
