In CentOS 6.7, if I start emacs from a terminal session, I always see

The message is also logged to .xsession-errors, and that occurs
regardless of how emacs is started. The same thing occurs with
SELinux in permissive mode.
Emacs version is emacs-23.1-28.el6.x86_64 .
Output from strace shows:
shmget(IPC_PRIVATE, 393216, IPC_CREAT|0600) = -1 ENOSPC (No space
left on device)
/proc/mounts contains:
tmpfs /dev/shm tmpfs rw,seclabel,relatime 0 0
and "df /dev/shm" shows:
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 8194164 172 8193992 1% /dev/shm
I can't identify any behavior problems that I can relate to this,
but it seems that something is wrong. Any clues as to what?
just a shot in the dark, but what do you have in
/proc/sys/kernel/shmmni ?
According to man shmget:
ENOSPC All possible shared memory IDs have been taken (SHMMNI), or
allocating a segment of the requested size would cause the
system to exceed the system-wide limit on shared memory (SHMALL).
