With the numbe of cameras you have it may be possoble you are running out of memory, tmpfs. Reduce the resolution and frame rate on your cameras. Also check the WIKI for the install instructions to see if you missed something.

Many thanks for your helping @bbunge

With the numbe of cameras you have it may be possoble you are running out of memory, tmpfs. Reduce the resolution and frame rate on your cameras.

Ok i try : i have stop 3 cams and decreases the quality of the main cam.
I test during some hours and post a new message with fresh informations from the battleground

Also check the WIKI for the install instructions to see if you missed something.

Hmmm it's my 3th install (on the same machine after reset) and the last install do not have this bug with full FPS and HD. But it's my first in Multi-Server mod with Database clustering.
All my installation procedure is indicated here in french : [Tuto/HowTo] Installer zoneminder sur ubuntu 16.04, [Tuto/HowTo] [Ubuntu] système distribué de caméra vidéos surveillance and [EN] [Tuto/HowTo] ZoneMinder Optimizations
I have this bug too on this install when i have only two cameras.
Some times when i change the config of one camera and save, ZoneMinder crash.


Sorry for my not terrible english.

Hi

I had a lot of errors similar what you have, like "zmc -m 4' has not stopped at 17/10/15 07:15:09. Sending KILL to pid 10474" or "'zma -m 2' exited abnormally, exit status 255]". Root cause for these errors was missing keepalive message in REMOTE RTSP protocol.

I manually forced keepalive messages by altering the code in zm_rtsp.cpp:

Line 365 in zm_rtsp.cpp
-- bool sendKeepalive = false;
++ bool sendKeepalive = true;

Line 508 in zm_rtsp.cpp
-- int timeout = 0;
++ int timeout = 60;

This change made the trick and now all my cameras have been now working over a week without any jamming.

I think that ZoneMinder monitor configuration should have an option to force keepalive message sending. Most likely my cameras are not the only ones needing keepalive messages...

Cheers

do you have the path for modify the file please?

[osk]

do you have the path for modify the file please?

here are all the steps I made to fix this error (Ubuntu 17.10):

Get build dependencies

Code: Select all

sudo apt build-dep zoneminder

Get ZoneMinder sources (To be able to get the sources you have to enable "Source Code" selection in "Software & Updates")

Code: Select all

apt source zoneminder

Fix the build error in zoneminder-1.30.4+dfsg/src/zm_comms.h by adding line

Code: Select all

#include <sys/uio.h>

Edit zoneminder-1.30.4+dfsg/src/zm_rtsp.cpp:
Line 365 in zm_rtsp.cpp
-- bool sendKeepalive = false;
++ bool sendKeepalive = true;

Line 508 in zm_rtsp.cpp
-- int timeout = 0;
++ int timeout = 60;


Compile sources

Code: Select all

apt-get --compile source zoneminder

Install compiled version

Code: Select all

sudo dpkg -i zoneminder_1.30.4+dfsg-2_amd64.deb

Really thanks Osk, i try tomorrow and post if it's working or not
With this method, what hapenning to zoneminder if i apt-get dist-upgrade ?
apt source zoneminder => that download in the current folder of the shell session?

With this method, what hapenning to zoneminder if i apt-get dist-upgrade ?

Well, my zomenider build last week was the first time I ever built something from sources, so I am not an expert here...

I suppose that apt dist-upgrade and even apt upgrade will replace the self-built zoneminder with distribution's original version unless you remove the default zoneminder package with apt remove.

apt source zoneminder => that download in the current folder of the shell session?

Yes, it downloads the sources to current directory. I used instructions from this page when I built zoneminder: https://askubuntu.com/questions/28372/h ... gh-apt-get

Code: Select all

sudo apt build-dep zoneminder

and

Code: Select all

apt source zoneminder

said : "You must insert some "source" addresses into your sources."

and theses instruction at the command "./do_debian_package.sh `lsb_release -a 2>/dev/null | grep Codename | awk '{print $2}'` `date +%Y%m%d`01 local stable" respond "Unknown option xenial, continue? (Y|n)n".

Run application "Software & Updates" and tick box "Source Code",
