Host connection and power state failure every minute on ESXi6.7u1 just for a secound

I have installed vsphere 6.7u1. And everything seems to work well with the exception that all the hosts fails randomly with error "Host connection and power state". This happend once a minute and after a secound everything is fine again. This means that everything else that happens to the hosts also fails. Even Remote Console for a VM to feezes. Has anyone else seen that problem?

It looks like we have found the problem. It was caused by firewall and Routing problem. 95% of the traffic was routed correct and accepted by the firewall, and 5% did not.

We use HP Proliant BL460Gen9 and HP 3Par Storage. This is the same as we use with vSphare 6.0 for Our Production, witch Works fine. We have just taken a few hosts from this enviroment and starting With 6.7u1.

In the vpxd.log, we can se that the problem last for about 1,5 secound.
