ZM droppes Camera

[markush]

Hi,

i recently setup a new vide station with ZM. I have used the instructions "Ubuntu 18.04 Easy Way". I have two cameras, Foscam 9900EP and a 9961 EP. Most times only one camera is working, sometimes both cameras unavailable and marked red and very rarely both working:

There is a 128GB SSD with the OS and 4TB HDD for Videofiles. There are 4 GB RAm Memory.

df -h /dev/shm/
Dateisystem Größe Benutzt Verf. Verw% Eingehängt auf
tmpfs 2,7G 633M 2,1G 24% /dev/shm


I'm totally confused Any hints for me?

Check the amount of tmpfs used. Also known as /dev/shm High camera resolution can use up a lot of RAM. Lower the camera resolution on both cameras.

df -h /dev/shm/
Dateisystem Größe Benutzt Verf. Verw% Eingehängt auf
tmpfs 2,7G 633M 2,1G 24% /dev/shm

Should be enough, isn't it?

[rockedge]

that looks okay as far as RAM...I have run into what you describe also before...I will look into my notes to see if I have a tip.

I feel like this is a permissions problem...... first thing to test please lower the camera resolution to something like 640x480 to see how the 2 cams run at this point

But sometimes both cams works well?!?

Have you looked up your notes?

Thanks!

My Network Configuration:

1 separate Networkcard for the cameras
172.16.0.240/16 - static ip

and 1 Network Card connected to the Network.
dhcp

Could this lead into the problems? A ping - command shows every time correct answers!

@rockedge: Changed resolution to 640x480, unfortunately no improvment

Still looks like a tmpfs issue.
What Linux distro and version?
How are you mounting the 4 TB drive?

[markush]

I'm using Ubuntu Linux Server Image, version 18.04.

Mounting of the 4 TB HDD (via /etc/fstab):
/dev/sda1 /video ext4 defaults,noatime 0 0

[bbunge]

You are better off using systemd to mount the drive. See
https://wiki.zoneminder.com/Common_Issu ... ive_or_NAS
With systemd you can hold the zoneminder start until the drive is mounted and the database server is running.

I have used an abbreviated version of this procedure to mount a second drive to /mnt/sdb1 and change the storage in Zoneminder to this location (/mnt/sdb1/zoneminder/events). viewtopic.php?f=38&t=28396
