Hi,
We are also facing similar issue. Oflate this error used to occur due to
time difference between VMs. Now the time sync issue has been addressed and
it was working fine for few months. VMware tools are also running fine.
Today again, the below error occurred and I noticed the time was perfect
between the VMs. The port configured on the farmIP stops responding which
brings down the LB service (LB IPs are reachable though while pinging)
Could you elaborate on how to check the vhid values? Also, is there any
other logs which can provide more insight on this issue?
