VMware vmotion fails with Error 195887167: Connection closed by remote host, possibly due to timeout

I am having this issue with any existing vm that I have , however, I created a SMALL test VM and it is able to VMotion BOTH ways , I only have this issue on one of the hosts in my cluster

I did not install a OS on the VM so maybe that is the difference?

I am considering reinstalling the ESX  on the one troublesome node is this a good idea?

no VMware Tools, so no heartbeats received from the OS, because there are no tools!

Best test is an OS, which you can install VMware Tools, and PING whilst vMotion is moving!

VMKPING is the tool to use to test communications between hosts!

ah Hancock my friend, how are things in the UK ? how is Brexit treating you?

I am thinking for some reason that the timeout was set to low , as I modified the fsr.maxSwitchoverSeconds to 600 and that solved the issue for one vm with CENTOS docker on it !!!

can this be set on a cluster level ?
is there any downside to this ?

thanks !!!!!!!

The default values should work for most environments, without changing!
BY any chance does the VM have a reservations or is extremely I/O intensive?
