</div><div>I am having trouble with using memcache as the keystone token backend. I have three keystone nodes running active/active. Each is running keystone on apache (for kerberos auth). I recently switched from using sql backend to memcache, while have memcached running on all three of the keystone nodes. </div>
<div><br></div><div>This setup would run well for a while, but then apache would start to hog CPUs, and memcached would increase to 30% or so. I tried to increase memcached cluster from 3 to 6 nodes, but in general the performance is much worse compared to sql backend.</div>
