Hi there,
we have some NetworkIssues with our SQL Server 2017 ( Windows Server 2019) Hosted at VMware ESXi, 6.7.0, 10764712.
Randomly the Connection to SQL Server were Dropped/Closed.
We actually have LRO disabled. Enable or Disable Software LRO for All VMXNET3 Adapters on an ESXi Host
But nothing changed. The Problem occurs randomly few times a day.
Anyone an Idea how to fix this ?
Hi,
change vNIC type from VMXNET3 to E1000 first, to eliminate a potencial problem with VMXNET3 and related offload feature.
Is it working stable now?
this weekend i changed vmnic back to e1000. problem still exists. randomly the connection are closed.
So maybe the problem lies on lower layer. Check how port group on virtual switch is configured:
- general teaming and loadbalancing policy settings,
- number of uplinks
Is this VM the only one that is using this portgroup?
