hi,
in /etc/fstab you got
Code:
shm /dev/shm tmpfs defaults 0 0
and a directory /dev/shm ? (might be created by udev)
i'm not sure what this will tell us but you can look at shared segments with the command
ipcs -m
i guess another issue could be size
i think shm is limited by default to half of physical memory
can be set to less in various ways like defaults,size=<>M i thnk
allocation certaily would fail if all is used up.
