Every 2-3 weeks all of the VMs on our ESXi server become unresponsive. I can connect to the host using the vSphere Client, but can't perform any actions. I can't reboot the host, check the hardware status or anything else. None of te VMs can be accessed either. The only way to get the server operational again is to push the power button and bring it all down. Once it's rebooted there aren't any errors anywhere, and everything looks normal. This issue has happened on 2 of our ESXi hosts, both are Dell PowerEdge R310 servers that are only 5 months old. Any thoughts on what the issue could be, or how to troubleshoot it?
