That is the problem... Which OS / Hardware are you using? Where/How did you get the httpd part of mod_cluster?

[naiauy]

Hi

Sorry for reply lated.

Which OS / Hardware are you using?

OS --> RedHat el5 on VM Player

Hardware --> Normal PC (i'm run vm player on windows xp)

Where/How did you get the httpd part of mod_cluster?

i download binaries linux2-x86 from http://www.jboss.org/mod_cluster/downloads/1-0-3-GA.html

i'm using apache 2.2.15 and compile by config below

./configure  --prefix=/AppServers/Apache2215 \

             --with-mpm=worker \

             --enable-mods-shared=most \

             --enable-maintainer-mode \

             --with-expat=builtin \

             --enable-proxy \

             --enable-proxy-http \

             --enable-proxy-ajp \

             --disable-proxy-balancer

Thanks in advance.

Auy.

I can't reproduce it with the bundle on the boxes I have.

Could you try with http://downloads.jboss.org/mod_cluster//1.0.3.GA/mod_cluster-1.0.3.GA-linux2-x86-ssl.tar.gz?

or do ulimit -c unlimited before starting httpd?

that should create a core.<pid> file.

gdb core.<pid> <path>/bin/httpd

where

Should tell where it core (make sure you are in the right thread, see gdb manuals).

[Fri Jul 02 18:06:46 2010] [error] proxy: CLUSTER: (balancer://mycluster1). All workers are in error state

Thanks.

[jfclere]

you have a typo somewhere... The balancer is mycluster and it seems you must have a ProxyPass going to mycluster1...

[jfclere]

Probably removing the ProxyPass solves the problem.

Hi Jean,

Thanks for your help. the issue was solved by edit excludedContexts

<property name="excludedContexts">${jboss.modcluster.excludedContexts:invoker,jbossws,jmx-console,juddi,web-console}</property>

Now, everything work properly.
