Set the maximum size of a shared segment to at least 1,048,576 bytes (1 MB) or more.

To set maximum size of a shared memory segment to 1 megabyte, add the following line to the /etc/system file:

set semsys:seminfo_shmmax=1048576

Set the minimum size of a shared memory segment to be less than the maximum size, preferably 1 byte.

To set the minimum size of a shared memory segment, add the following line to the /etc/system file:

set semsys:seminfo_shmmin=1
