Frequent hangs with VMware

[josh.townsend]

I'm using the free version in my VMware vSphere 5.5 lab but am running into problems. All of my ESXi hosts lose connectivity to storage and go into an APD/PDL status. I'm pretty sure the problem is not with ESXi. I've attached the error log from StarWind - could somebody look at it and see if they can identify the problem? The Windows server that StarWind is running on doesn't show much of a load as far as CPU/memory go. A bit of disk queue/latency, but nothing too high. Windows event log doesn't show any issues. Windows Explorer.exe seems to hang at the same time that hosts loose connectivity to iSCSI.

Also, I tried to apply a valid 30-day trial license (expires in April 2014) but get an error that the license is expired. Any ideas?

I"m on the latest build (6399)

Thanks,
Josh

Hi!
Did you try disabling VAAI for the StarWind targets?
The version you're running doesn't fully support VAAI so It's recommended to disable it.
