Hi all, I have 3 Controller deployment in HA using Juno/Centos 7, based on this howto: *https://github.com/beekhof/osp-ha-deploy/blob/master/HA-keepalived.md <https://github.com/beekhof/osp-ha-deploy/blob/master/HA-keepalived.md>* Usually after some 2/3 weeks I start to have CPU high load issues on my controllers as you can see below. I have to restart all my services to everything get back to normal. Some pointers: 1º This can happen in any controller, so I don't think it's a hardware issue. 2º My cloud is not in production yet, so I don't have much usage. 3º I only see high load in related openstack services. Can anyone provide me some tips to figure out what's wrong here? Thanks. *top - 05:05:38 up 28 days, 4:02, 1 user, load average: 12.79, 12.18, 12.14* *Tasks: 420 total, 10 running, 410 sleeping, 0 stopped, 0 zombie* *%Cpu(s): 82.6 us, 16.1 sy, 0.0 ni, 0.0 id, 0.0 wa, 0.0 hi, 1.3 si, 0.0 st* *KiB Mem : 32732120 total, 19646776 free, 6891364 used, 6193980 buff/cache* *KiB Swap: 16457724 total, 16457724 free, 0 used. 23890352 avail Mem * PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 22270 root 20 0 161808 20516 4364 R 24.9 0.1 0:08.24 cinder 19234 swift 20 0 246148 15076 1620 R 24.7 0.0 2:25.64 swift-object-au 22268 root 20 0 178528 22904 5000 R 24.2 0.1 0:08.48 keystone 33342 keystone 20 0 468852 69132 4148 R 24.2 0.2 539:01.19 keystone-all 22264 root 20 0 141596 19652 4076 R 22.7 0.1 0:07.56 neutron 22262 root 20 0 170680 21736 4924 R 19.7 0.1 0:08.24 keystone 22537 root 20 0 203540 9884 3656 R 19.7 0.0 0:01.19 neutron-rootwra 22273 root 20 0 141504 19800 4076 R 19.5 0.1 0:07.63 glance 33423 neutron 20 0 453068 73784 2024 S 16.0 0.2 26:53.02 neutron-server 33338 keystone 20 0 468880 69124 4148 S 11.5 0.2 540:48.66 keystone-all 22288 rabbitmq 20 0 640756 17068 2512 S 11.2 0.1 0:04.12 beam.smp 32813 glance 20 0 352124 55292 5928 S 9.2 0.2 661:41.51 glance-api 32863 nova 20 0 385864 74056 7196 S 9.2 0.2 673:00.23 nova-api Regards, Pedro Sousa
