Maybe, but see below.

Here is your clue, right there.

compare:
cat /proc/sys/kernel/shmmax
on the Debian system with the redhat system.
To alter the setting, e.g.:
echo 1000000000 > /proc/sys/kernel/shmmax
will allow a segment up to one billion bytes.
The error (from above):
Unable to attach 3 segments totalling 566165504 bytes
will help determine the value.
If you reboot your computer, you will lose that setting so you will have
to put it in a local init script.
