Although the default failure stickiness is -30, the group has a failure
stickiness of -100. I would like to failover after 3 or 4 failures.
My test with 15 stop commands was "just to be sure."

I actually do have monitor operations on both, I accidentally sent out
an old cib.xml, updated file attached. Previous showscores.sh output is
correct for this cib.xml. It behaves as described in the last e-mail
even with monitor operations on IPaddr2 and jboss.

Uh oh. I definitely have 2.1.3 with the crm_failcount bug, but I didn't
think this would affect score calculation. I didn't install a pacemaker
package, I used the CentOS4 extras RPMs. I hope CentOS4 / RHEL4
packages can be released. I could not rebuild RHEL5 packages from the
openSUSE ha-clustering repository due to this:
configure:3065: gcc -c -O2 -g conftest.c >&5
conftest.c:2: error: syntax error before "me"
configure:3071: $? = 1
configure: failed program was:
| #ifndef __cplusplus
| choke me
| #endif
Should I seek an alternative to these CentOS 4 extras RPMs?

I hacked it together, it's ugly. Hope it's useful to you, although it's
tailored to a very old jboss release 3.0.8, with some customizations to
support multiple instances of jboss on different ports. Relies on ps,
awk, egrep, and curl, only tested on RHEL4. You'll want to change the
HTTPCODE check with an URL for your servlet (or modify to use jmx-console).
