Hi, Digging the issue with Galera, I found that our environments have very high RAM utilization which leads to the problem during environment deployment. For instance "HA deployment + neutron/GRE" requires almost 2.6-2.7 GB during deployment (corosync+mysql+puppet++rabbit+neutron+ovs+openstack services). I found high swap in/swap out usage during deployment with very high load average. This creates many sporadic issues with some services. They time out in random place making our debugging very hard. I would like to review our policy for CI environment and increase RAM (at least for bvt tests) to 3 GB.
