Public bug reported:

Horizon uses memcached servers for caching and it connects to all of
them directly. So if one of them is not responding, it may lead to
delays in Horizon operations.

Workaround:

1) Edit /etc/openstack-dashboard/local_settings file and temporarily
remove the problem controller IP:PORT from LOCATION line in CACHE
structure:

CACHES = {
    'default': {
        'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION' : "127.0.0.3:11211;127.0.0.5:11211;127.0.0.6:11211"
    },

2) Restart apache web server
