Ubuntu 9.10, 2 cam 640x480. 1,5gb ram shared mem problem

execcr · Post by **execcr** » Mon Dec 07, 2009 3:58 pm

Hi everybody,
once week ago i set up this system for use it with zm in my home.
I used an old pc that was without a work...

AMD Athlon64 3200+
1,5 gb of ram, DDR, set up with 1gb slot, 2*256mb
Motherboard asus
PCI dvr card with 8 input BNC, 240 fps total

SO: Ubuntu 9.04
ZM 1.24.2

I install zm with the guide in the wiki, checking all pass
Then i set the permission for the video device using 777

I configure the first cam with these settings
device V4L2 /dev/video8
res 640x480
PAL
GREY (tried also RGB24)

the second is the same, change the path /dev/video5

The problem is that after one hour or two one camera stop working
In var/log/message i see this error:

Code: Select all

Dec  7 16:36:05 server-amd zms[16346]: WAR [Unable to store frame as shared memory invalid]

If i restart zm everything works again for some time, then one camera goes black

i change the sysctl.conf setting after zm install to:

kernel.shmmax=222184000
kernel.shmall=310000

But i have always shared memory problem.

In webmin running process panel i see that on 1,4gb of ram 1.2gb are free.

if i launch top from terminal it tell me differnt values: 1,2gb of ram used, 222mb free.

I dont know how i can figured out... i tried to change sysctl values, adding more and more ram, but nothing

IPCS -l tell me

Code: Select all

fede@server-amd:~$ ipcs -l

------ Limiti della memoria condivisa --------
numero massimo di segmenti = 4096
dimensione max seg (kbyte) = 216976
max total shared memory (kbytes) = 1240000

------ Limiti di semaforo --------

numero max opz. per chiamata semop = 32

------ Messaggi: limiti --------

some help is very appreciated!!!
thanks

i tried to recompile zm with mmap enabled.

Seems better!

one question; i have to rewrite original ubuntu shmmax and shmall in sysctl.conf back?

execcr · Post by **execcr** » Tue Dec 08, 2009 9:18 pm

No way... camera goes again black!

i set sysctl.conf to kernel.shmall=393216
and kernel.shmmax=393216000
1,5gb ram DDR.

i have 3 cam operating as 640x480 in grey scale, v4l2 device, at 10fps.

Why one cam goes always black before some time???

I have to add more ram?? In top every zmc process take 120mb of ram, and i have only 3 of these!!

please, someone give me some advice...

just dont use ubuntu 9.10 , it has plenty of conflicts wth zoneminder, use a different distro or ubuntu 8.04. I wasnt able to use any version of zoneminder on ubuntu 9.10.

I've got same problem. Did you fix, how?
I wrote my server's system properties below (to my signature)
Both of two cams operating as 640x480 px in rgb24, v4l1 at 20fps

At first system start, the one of cams (mon1) was black and other one(mon2) was working. But now, mon-1 still black and mon-2 is not working.

I've got a 9.10 running 1.24.2 dandy (at lower loads than it was at 8.0.4), aside from not being able to create video (yet), but that's probably something I screwed up compiling ffmpeg.

What is my fault?

There isn't enough info to diagnose the problem.

run dmesg and check for driver problems, they will show up towards the end if this is the case.

Check your interrupts and make sure there is not a conflict -> cat /proc/interrupts

Turn on debug as described in the troubleshooting/Documentation in the wiki as well as the many posts.
