Clustering Tomcat

[Ben <ne...@gmail.com>]

Hi

I'm trying to configure clustering of 2 Tomcat servers on a single
CentOS 4 machine. When I start the first Tomcat, I get error  messages
like this in the catalina.out log file:

org.apache.catalina.cluster.mcast.McastServiceImpl$SenderThread run
WARNING: Unable to send mcast message.
java.net.SocketException: Operation not permitted
        at jrockit.net.SocketNativeIO.send(Ljava.io.FileDescriptor;[BIILjava.net.InetAddress;II)I(Unknown

        at org.apache.catalina.cluster.mcast.McastServiceImpl$SenderThread.run(McastServiceImpl.java:264)


I am using JRockit 5.0_02 and Tomcat 5.5.9.

Where can I find more information about this error?

Thanks,
Ben
