Version 7.31.UC5 memory question

Howdy, I am installing my 7.31.UC5 upgrade and have a question about the memory. I see a message about rounding the memory up, which is find with me, but does anyone know which onconfig parameter this is using?

On some OS's Informix rounds shared memory segments requests up to the system memory page size for efficiency and sometimes because the OS will allocate that only full pages anyway. Art S.
