Usage
The SHMNOACCESS configuration parameter is used to avoid specific range process addresses, which in turn avoids conflicts with operating system libraries.
Each address in each
range must start in hexadecimal format. Each address in a range must
be separated by a hyphen and each range must be separated by a comma,
as the following example shows:
SHMNOACCESS 0x70000000-0x75000000,
0x7A000000-0x80000000
