I'm running Zoneminder 1.24.2-8 which I apt-get'd on a Debian box from it's standard repositories. Using an Edimax IP camera as a source.

Had a few issues with paths that meant I had to change the symlinks in /usr/share/zoneminder rather than change the apropriate fields in the options/paths box (no idea why but playback of captured clips wouldn't work unless I changed the symlink /usr/share/zoneminder/images to point to my mass storage directory manually)

...but apart from that everything seems to work. That is, until I click on the zone associated with the camera, drag the corners of the motion detection box to cover only part of the image and click save and restart zoneminder.

If I then click on the camera the window pops up but I just get Firefox's broken-image icon instead of my camera's stream. At the same time I get this error in apache's error.log:

The file zms-171375s.sock doesn't exist but the path to it does and is chmod'd 777, so if something's prevented zoneminder from creating the file it shouldn't be permissions.
Note that the error log has errors about depreciated functions but from googling I gather they're "normal".

If I delete the zone then create a new one which defaults to 100% of the image covered, everything starts working again.

Has anyone seen anything similar?

I've run the same Zoneminder setup with a local USB camera and I don't get the problem.
Looks like it's IP cam specific.

I've got the same issue... Here's some additional info.

Additionally, I've noticed that when I open a camera to monitor, if I 'ls -l /tmp' repeatedly, I get:

Code: Select all

# ls -l /tmp/*.sock
srwxr-xr-x 1 www-data www-data 0 2011-05-17 18:22 /tmp/zmdc.sock
srwxr-xr-x 1 www-data www-data 0 2011-05-17 18:33 /tmp/zms-139718w.sock

And then after about 5 sec, the zms-*.sock file disapears. Then, about 5 seconds later, it comes back... and so on, and so on, as long as the webcam window is open.

Here is the zm_debug log from when I opened the webcam viewing window:

Areyou saying that your zmc process is continuously restating or just once when you do things with the zones?

Oh, sorry... Actually, it seems to be crashing every 10 minutes. Whether or not I open a monitor.

It also seems to start the crashing (signal 6) after adding more than 2 zones.

It looks like I have have 2 zones (of any type), but as soon as I add the third, I get the signal 6 crashing. Then, if I remove zones until I get back to 1 or 2 zones, it stops crashing.

Weird.

The simplest way of tracking this down may be to either go to Options->Debug and switch on extra debug for zmc_m3 (yes it is meant to be an underscore). Set it to level 5 for now. Then you should get debug logs dumped (probably in /tmp unless you have configured otherwise) which might contain someuseful information.
