Subj: FreeBSD (V4.2) Shared memory
To: freebsd-questions@freebsd.org
From: raymond@one.com.au
On 4.2-RELEASE i386, I have attempted to build 268697600 bytes (65600 pages)
of shared memory with the config options:
options SHMALL=65600
options SHMMAXPGS=65600
After a build, ipcs reports as follows:
%ipcs -TM
shminfo:
shmmax: 268697600 (max shared memory segment size)
shmmin: 1 (min shared memory segment size)
shmmni: 96 (max number of shared memory identifiers)
shmseg: 64 (max shared memory segments per process)
shmall: 65600 (max amount of shared memory in pages)
Yet, I can't seem to get my code to connect to a shared memory segment
greater than 64KB.
Am I missing something (like a maximum size)?
