Just to add to this, I meant to say above that we lost all access to this VCS Expressway (running x7.2.3) which became completely unresponsive to SSH and HTTPS, although we could still ping the box. Traversal zones failed and hence no call could pass. Luckily, we had someone on site that could physically power-down and restart the box. When it came up we saw this error.
I have seen this several times on VCS platform. Especially when running VM.
I have to power cycle hardware or VM (clean shutdown when possible) and it usually resolves the issue.
I think there is a bug reference somewhere but I cannot locate it. I believe when on VM platform this is usually do to the overprovisioning of resources on the host. Usually HDD space. If the issue persists and you are running VM. You may want to look into making sure the HDD on the VM was thick provisioned at time of deployment, and that other system resources are not over provisioned.
