    When you migrate a virtual machine, the process fails with the error:

    Operation timeout

    When you create snapshot a virtual machine, the process fails with the error:

    An error occurred while taking a snapshot: msg.snapshot.error-DUMPER.

    An error occurred while saving the snapshot: msg.snapshot.error-DUMPER

    This error only on one server, but on all servers in vmkernel.log i see this:
