The operating system command 'ipcs -ma' reports more than one shared memory segment for ASE when "max memory" is configured for larger than 2 terabytes. The first shared memory segment reported by ipcs is exactly 2 terabytes.
$ ipcs -ma
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x9601c479 98307 sybase 600 2199023255552 1
0x9601c485 131076 sybase 600 1031865892864 1
The first shmid is exactly 2 terabytes and the second shmid is 961GB. The sum of both shared memory segments represents the "max memory" configured to ASE.
This report of maximum single shared memory segment size of 2 terabytes is the default and expected behavior.
