Cinelerra: MWindow::init_shm: /proc/sys/kernel/shmmax is 0x1000000 It should be at least 0x7ffffff

I‘m trying to use Cinelerra video editing and compositing software under Linux operating systems. However, I’m getting the following error:

MWindow::init_shm: /proc/sys/kernel/shmmax is 0x1000000.
It should be at least 0x7ffffff for cinelerra.

How do I fix this problem?

Linux: Neighbour Table Overflow Error and Solution

Posted on in Categories , , last updated December 19, 2011

I setup a CentOS Linux based Linux server running as a gateway and firewall server. However, I’m getting the following messages in the /var/log/messages log file:

Dec 20 00:41:01 fw01 kernel: Neighbour table overflow.
Dec 20 00:41:01 fw01 last message repeated 20 times

OR


Dec 20 00:41:01 fw03 kernel: [ 8987.821184] Neighbour table overflow.
Dec 20 00:41:01 fw03 kernel: [ 8987.860465] printk: 100 messages suppressed.

Why does kernel throw “Neighbour table overflow” messages in syslog? How do I fix this problem under Debian / CentOS / RHEL / Fedora / Ubuntu Linux?
