A specified parameter was not correct: spec.location.host

CF 4.1 reports often error when provisioning a vsphere VM :
[----] E, [2017-02-06T11:05:20.427051 #16877:80b998] ERROR – : Q-task_id([miq_provision_1000000002317]) State= running on_error raised exception: <invalid method calling syntax: [update_provision_status(status => ‘[RuntimeError]: A specified parameter was not correct.
spec.location.host’)]>

When we restart CF, it works again.
