Can't switch 4th camera to modect

Hi!

My Ubuntu Linux 9.04 server edition had 3 cameras (two on a bt8x8 card, one IP camera) - worked like a charm.

I added a 4th camera, same type IP camera like the other one. The problem is, that I can't switch it to Modect. The source text on the interface keeps staying orange instead of turning green.

I can see all the monitors well in my montage view, all do modect very well except this last one.

In the logs I see this repeatedly:

Code: Select all

Oct 21 15:59:52 zm zmdc[13688]: INF ['zma -m 4' starting at 09/10/21 15:59:52, pid = 14127] 
Oct 21 15:59:52 zm zmdc[14127]: INF ['zma -m 4' started at 09/10/21 15:59:52] 
Oct 21 15:59:52 zm zma_m4[14127]: INF [Debug Level = 0, Debug Log = <none>]
Oct 21 15:59:52 zm zmdc[13688]: INF ['zma -m 4' crashed, signal 6]

I tried to disable the third camera completely and enable the 4th instead, no success.
I tried to delete and re-create it, no success.
I tried to use the third IP camera for this monitor, doesn't work.

Any ideas?

Hi,

Once I've seen that (maybe other problem). I use IP camera, but based on a small protocoll problem (EOF in the first connecting phase) zoneminder can't get the stream from it. I use openRTSP and ffmpeg input. It works only if every setting in the chain are the same. On the camera, openRTSP, and ZM. Even an FPS misconfiguration can cause a zmc error.
I hope this will help.

Kind Regards,
BaZso

This is not the case, because in the monitor or montage view the live picture is shown very well. The recording part is the one which doesn't work.

Any ideas where should I look, and for what?

Turn up the debug level and logging and see what that gets you. I don't know what signal 6 is off the top of my head.

FPS under recording and viewing can have different settings, so can be a problem

If monitor is working and modect/mocord is not, I can think of two possibilities. Either you need to allocate more shared memory or there is something wrong with the zones for that monitor.

Try allocated a little more shared memory and try replacing the zones for that monitor with a simple zone.

I only have simple default zones, no extra things. I didn't modify anything inthere.
My box has 4GB of RAM, and shared memory sizes:

#cat /proc/sys/kernel/shmmax

# cat /proc/sys/kernel/shmall

What debug level do you recommend?

Ah, got it:

Code: Select all

11/07/09 23:04:13.082562 zma_m5[27916].ERR-zm_monitor.cpp/487 [Can't make events/4: Permission denied]
11/07/09 23:04:13.082808 zma_m5[27916].FAT-zm_monitor.cpp/494 [Can't symlink '4' to 'Napp': Permission denied]

For some reason the events directory was owned by root, and zm didn't have permission to create sub-folder for the new camera.

Strange, because the other cameras had no problems from the beginning...
