During start-up, Open Server may return the following error if there are multiple Network Interface Cards (NIC) on your server:
WARNING: SRV_CURPROC is null, msgno = 16240
Workaround: Create one master/query entry for each Open Server. You no longer need to have entries for each NIC in the interfaces file with version 12.5.1, because it now does a wildcard bind to every network interface on the server.
