Hello,
we have a vSphere 6 infrastructure composed by multiple ESXi hypervisors (6.0u2) and NSX 6.2.7, we are receiving a lot of "Host Error" events on each host from the vdrb component.
We checked the vmkernel.log and the problem is always the same:
2017-06-13T02:38:05.027Z cpu5:33309)vdrb: VdrTimerRemove:254: SYS:VdrTimerRemove: Deleting timer that has already fired TimerEntry=0x430695760f40, fn=0x41800b43c950, arg1/arg2=73695556391744/256

Do you have any idea what could cause them?
Thanks in advance.
