Dmitri Chebotarov commented on VCL-609:
---------------------------------------
I've encountered this issue on VCL 2.3. Firewall settings fail for Windows
reservations. For now I've removed lines checking for $exit_status (above)
> Reservations fail if cat command returns non-zero exit status when retrieving
> contents of /etc/hosts on management node

> The get_computer_private_ip_address subroutine in Datastructure.pm retrieves
> the contents of /etc/hosts on the management node using the cat command.
> Occasionally this command returns a non-zero exit status even though the
> contents were retrieved causing the subroutine to return null unnecessarily.
