Bug Description
We face a grievous issue that all controller nodes hang in MOS 9.2 env. Cann't ssh and all openstack service block.
Env describe is below:
1. Three controller nodes、three network nodes、three rabbitmq nodes. We separate network and rabbitmq service from controller nodes.
2. We have 300 openstack nodes and about 2700 VMs.
Issue describe is below:
1. all controller、
2. use cmd "strace" ssh service at the controller node, we find ssh service block at "connect(7, {sa_family=
3. if we stop rsyslog service all nodes can access and all openstack service re-work.
So what is the root cause? Do anyone face the same issue?
