CineLerra Shared Memory Patch

petelogan · 01-23-2012, 09:57 AM

Cinelerra gives an irritating but not fatal notification that it wants the shared memory allocation in /proc/sys/kernel/shmmax increased to 0x7fffffff

Doing it by session works, but it should be possible to make the change permanent.

Google gave me this on a Gentoo forum but I have zapped two files of that name under Suse 12.1 and it still loads the default, so I assume it must be defined somewhere else in Suse.

Does anyone know where the correct .conf file is that will enforce this change ??

Thank you for any help you can give, whether it be the answer, or suggestions where to look.

Pete

/etc/sysctl.conf is the right place to have values survive reboots.
How did you test it did not stick or work?
Or maybe you didn't add the right line or the right way?

Code:

]$ su -l
CURVAL=($(/sbin/sysctl kernel.shmmax)); NEWVAL=$[${CURVAL[2]}*2]
sysctl -w kernel.shmmax=${NEWVAL}
echo "kernel.shmmax = $NEWVAL" >> /etc/sysctl.conf
# Test it (after reboot?):
grep -q $NEWVAL /proc/sys/kernel/shmmax && echo "set OK"

//NTLB

Thanks very much. I'll give that a go tomorrow when I get a minute.

Thanks again.
