[Pacemaker] resources are restarted without obvious reasons

Hi,
It seams that it happens every time PE wants to check the conf
09:23:55 crmd: [3473]: info: crm_timer_popped: PEngine Recheck Timer
(I_PE_CALC) just popped!

and then check_rsc_parameters() wants to reset my resources

09:23:55 pengine: [3979]: notice: check_rsc_parameters: Forcing restart of
pbx_02 on node-02, provider changed: heartbeat -> <null>
09:23:55 pengine: [3979]: notice: DeleteRsc: Removing pbx_02 from node-02
09:23:55 pengine: [3979]: notice: check_rsc_parameters: Forcing restart of
pbx_01 on node-01, provider changed: heartbeat -> <null>

looking at the code I can't conclude where the issue could  be, in the
actual conf or  I am hitting a bug
static gboolean
check_rsc_parameters(resource_t *rsc, node_t *node, xmlNode *rsc_entry,
             pe_working_set_t *data_set)
{
    int attr_lpc = 0;
    gboolean force_restart = FALSE;
    gboolean delete_resource = FALSE;

    const char *value = NULL;
    const char *old_value = NULL;
    const char *attr_list[] = {
        XML_ATTR_TYPE,
        XML_AGENT_ATTR_CLASS,
        XML_AGENT_ATTR_PROVIDER
    };

    for(; attr_lpc < DIMOF(attr_list); attr_lpc++) {
        value = crm_element_value(rsc->xml, attr_list[attr_lpc]);
        old_value = crm_element_value(rsc_entry, attr_list[attr_lpc]);
        if(value == old_value /* ie. NULL */
           || crm_str_eq(value, old_value, TRUE)) {
            continue;
        }

        force_restart = TRUE;
        crm_notice("Forcing restart of %s on %s, %s changed: %s -> %s",
               rsc->id, node->details->uname, attr_list[attr_lpc],
               crm_str(old_value), crm_str(value));
    }
    if(force_restart) {
        /* make sure the restart happens */
        stop_action(rsc, node, FALSE);
        set_bit(rsc->flags, pe_rsc_start_pending);
        delete_resource = TRUE;
    }
    return delete_resource;
}
