Okay, here's the setup. I'm running ZM in a docker. I can add the first remote monitor (axis 207) totally fine with:

Remote host name: myuser:mypass@192.168.0.22
Remote host path: /axis-cgi/mjpg/video.cgi?resolution=640x480

I'm not sure what's going on and google warrioring didn't turn up much. I have posted instructions (if you're semi familiar with docker) at the bottom to getting this if you need to inspect it. The install is on ubuntu 14.04.
first monitor works all honkey dory when I view it. The second however throws:

The ZM docker setup I'm using is here on github:
QuantumObject/docker-zoneminder/

If you'd like to just use the one I've already built feel free to grab it and run it with:
sudo docker run -d -p 80:80 hrwebasst/zoneminder

if you are wanting to take a peek inside of the container you can install nsenter:
sudo docker run --rm -v /usr/local/bin:/target jpetazzo/nsenter

and then a sudo docker ps will give you something like this:
e430db294535 hrwebasst/zoneminder:latest "/sbin/my_init" 4 seconds ago Up 4 seconds 0.0.0.0:80->80/tcp zoneminder

using sudo docker-enter e430db294535 will give you access to inside of the docker instance. (the hash value will be different for you)

And for the record yes my remote host name has http on it but this stupid damn forum kept telling me it was "too spammy" and I had to remove anything that remotely looked like a url.

keeping posting - I had the same issue in my first few posts.

So I had a similar issue when I started with ZM. First camera worked great, second one bonked just like yours with similar messages. The problem was I was running out of "mapped memory" (the space inside /var/run). Increasing shm does not make a difference as newer versions use mmap (yet another example of outdated information hanging around in various wikis)

a) Try this, while running your first camera do a "df -h" on a terminal and please post the results
b) How much memory do you have?

So this seems to be your problem. You are out of /dev/shm space.
Now you are running ubuntu 14 right? And I assume ZM 1.27 or above?

In my case (Ubuntu server 14.04) /dev/shm is a pointer to /run/shm (or /var/run/shm which in turn points to /run/shm). In other words, they are all the same.

Can you check the following:

a) Confirm that /dev/shm does indeed point to /var/run/shm or /run/shm

b) start zone minder with that one camera that works and go to /dev/shm

-- do you see a file there called zm.mmap.<whatever> ?

I just want to make sure your zone minder is using mapped memory and not shared memory.

If you do see it in /dev/shm, then you need to increase mapped memory space, not shared memory space.

wow so it looks like this is the problem the whole flipping time!

umount /dev/shm
mount -t tmpfs -o rw,nosuid,nodev,noexec,relatime,size=2048M tmpfs /dev/shm

fixes this problem. Is there a way around this? Any way we can have zoneminder allocate memory differently? the host has 8gb

Credits to asker:

## add fixed RAM disk to /etc/fstab (/dev/shm size to use 25% RAM, increase as needed)
sudo vi /etc/fstab
tmpfs /run/shm tmpfs defaults,noexec,nosuid,size=25% 0 0

Hope it helps,
