rc = 1 is not an LSB compliant response to a status check.  I assume you are using the LSB init script for Apache in your cluster?

Test the init script as indicated here:
http://clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explained/ap-lsb.html
and here:
http://oss.clusterlabs.org/pipermail/pacemaker/2010-July/007008.html

Could possibly be related to this too but I doubt it:

This looks odd too... not only that it's not running but also the double //
But figure out the monitor problem first then re-evaluate

Your cluster config would also help...
