The database server that you tried to access or a path that was specified in your DBPATH environment variable is located on an NFS-mounted file system. However, the database server or client application encountered an error accessing the NFS-mounted table file /etc/mtab (or, on some operating systems, /etc/mnttab). This condition probably occurred because your account does not have read permission for the file. Contact your system administrator, and have the file made readable to public.
This message appears with Version 6.0 and later.
-916 Cannot open /etc/mtab.
The database server needs to check the system configuration file /etc/mtab to verify the location of a file system. However, it got an error when it tried to read that file, probably because your account does not have read permission for it. Contact your system administrator, and have the file made readable to public.
This message appears prior to Version 6.0.
