zmdc.pl: can`t find child with pid of 29448 ..

Managed to get zm up and running, previous problems was related to a bad perl installation. I still get some errors when running the perl-modules tests, but I`m not sure if that`s the problem.
Running arm-xscale-be
mysql 3.23
perl 5.6.2
When I try to stream video I don`t get the feed.
tail -f /tmp/zm*.log /var/log/messages while running zmpkg restart gave this output:

So I got a "shared memory error", and a "cant find child with pid" error.. I have not installed FFMPEG, but that shouldn`t be neccessary just for viewing the cams? Oh and the cam does work when I access it directly through my firefox.
Ideas? Appreciate any help!

Which version of ZM are you using? I would also suggest checking your zones to make sure they are not broken, especially if using an older version of ZM than 1.22.2.

Forgot..
1.22.2

Hmm, it's very unusual to see everything crashing. Can you run with debug up a bit, or run one of the zmc daemons directly in gdb?

could this be as simple as a permission problem? ZM is installed as root, same with mysql and perl.

I have now installed gdb, and I got this:

Yuck! I would try a full rebuild ('make clean' before make) and also check that the DB doesn't have errors (mysqlcheck).
If you still get it we will try something else.

Now I have completely reinstalled zoneminder, and also run mysqlcheck which shows nothing wrong.
Still zmdc.log gives this:

Also I get the same segmentation fault as before when trying to run zmc by itself..
Any ideas?

is it recording, ie if you set to record or mocord do the events increase. If this was a standard system i would sy check the paths and remove nph- from the streaming patrh as it looks like it cant get images from the path supplied, but this isnt a normal distro and im unsure
Sorry

Seems like it doesn't matter wheter I use record or monitor.. Looks to me that zmc is crashing with "signal 10" (what does that mean?), then zmwatch is trying to use the pid that zmc created before it crashed and gets shared memory error.
Another thing corey mentioned in another topic is that the kernel needs v4l2 - I doubt that it has that installed as it is created for embedded devices.. but do I really need it when all I use is network cameras (Axis 206M)?

You should not need v4l2 in the kernel if you don't plan on using the hardware (capture cards).
As far as your error, The only thing I can suggest is to increase your debug levels for _zmc and check the debug logs created for better detail.
Regards,
Corey

thanks for all the help guys!
Going to try to install a different version of perl (yet again) as zmc only displays "segmentation fault" when run.. Will let you know how it goes!

I don't think it's a perl issue as zmc doesn't use perl. It looks more like a database problem if anything.

I tried to use a remote database running MySQL 5.0 (the arm uses 3.23) but the same problem.. ZMC does'nt want to start. As printed earlier, when running gdb, it says there's something wrong with zm_config.cpp, and it can't access memory.
The segmentation fault occurs even when zmc is run without variables, on my other pc it outputs some text on how to use it.

Found out that if I restart the machine and run zmc/zma/zmu before trying to start zmpkg.pl, everything is fine. After zmpkg.pl is run, everything starts crashing and they give segmentation fault when run seperately even after stopping zmpkg.pl.. maybe you're right about the database thing, but I tried databases both locally and remotely.. I'm drawing blanks here:(
