[ClusterLabs] Pacemaker Active-Active setup monitor problem

[Alex]

Hi all,
I am having a problem with one of our pacemaker clusters that is running in an active-active configuration.
Sometimes the Website monitor will timeout, triggering and apache restart that fails. That will increase the fail-count to INFINITY for the Website resource and make in un-managed. I have tried the following changes:
pcs property set start-failure-is-fatal=false

increasing the stop timeout monitor on the Website resource:pcs resource op add Website stop interval=0s timeout=60s

Here is the resource configuration: Resource: Website (class=ocf provider=heartbeat type=apache)  Attributes: configfile=/etc/httpd/conf/httpd.conf statusurl=http://localhost/server-status   Operations: start on-fail=restart interval=0s timeout=60s (Website-name-start-interval-0s-on-fail-restart-timeout-60s)              monitor on-fail=restart interval=1min timeout=40s (Website-name-monitor-interval-1min-on-fail-restart-timeout-40s)              stop interval=0s timeout=60s (Website-name-stop-interval-0s-timeout-60s)
Here is what I see in the logs when it fails:

I dont see that pacemaker is waiting for 60 seconds for the apache to stop.
Has anyone encountered something like this before? Or am I missing something in the configuration?
Thank you,Alex
