During incremental change query, we are calling the QueryChangedDiskAreas API with a changeId, it throws a file fault.
The VM's vmware.log doesn't give a clue about the failure, but the failure entries are seen in the ESX hostd.log.
Following is a sample error from the log:
[7EEA1B70 verbose 'Default' opID=749a6dd4-1a user=vpxuser:MyDomain\MyUser] AdapterServer: target='vim.VirtualMachine:3', method='queryChangedDiskAreas'

Please help with a solution. Thanks in advance!
