For some reason my capture dameon is restarting every 10 seconds. I just installed Fedora Core 4 and then installed 1.21.1. My network video capture is working correctly, but only updates once every 10 seconds. I installed 1.21.0 just for kicks and it works like a charm, so the problem is particular to 1.21.1.

Do you have anything from /var/log/messages or anywhere that might give an indication of any errors?

Phil

Here are the interesting logs:
==> zmdc.log <==
'zmc -m 1' stopping at 05/06/15 19:59:35
'zmc -m 1' died at 05/06/15 19:59:35

'zmc -m 1' starting at 05/06/15 19:59:35, pid = 17157

==> zmwatch.log <==

'zmc -m 1' starting at 05/06/15 19:59:35, pid = 17157

and then /var/log/messages that coinicides with the event

Jun 15 20:00:16 localhost zmc_m1[17587]: INF [Got TERM signal, exiting]

That's all I get. That and when I view the monitor I see 0.00fps and the one shot per ten seconds in the montage.

After watching the logs scroll by for about 5 minutes I noticed this in /var/logs/messages, a continueing stream of these messages:

Can you increase the debug level of zmc and rerun it from the command line? It seems that it's getting an invalid response from your camera.

Phil

zmc -h doesn't show how to set the debug level and I didn't see it anywhere in the options of the application. How do I run zmc in a higher debug level?

Hi jet.

Just define a higher debug level via enviroment variable, like this:

export ZM_DBG_LEVEL_zmc=4

Phil, I have seen in the manual, that you can set the debug level via signals - does it mean you can kill -(something) zmc, and it will change the debug level on fly? What is the correct command form of "kill" then it should be?

Okay zmc -m 1 (my only monitor) at debug level 4 puts a fast stream of this into the zmcd.log file

I'm using a DCS-900 which I've never had problems with before and still works fine with 1.21.0

These look fine. Are you saying the previous ERR messages are no longeer displayed?

Phil

The original errors still happen, but that last log was just with the zmc running alone. I'm not sure how to run zmc in error mode and still run all the other processes? Do I manually start up zmc with the env set for debugging, and then start the other processes through the web gui?

zmc is the primary process for capture so it doesn't actually need any other processes to run, to does whether any are affect what errors it might produce.

Phil

With zmc started manually with debug level 4 and the rest of the processes started via the web gui here is an except from tail -f /tmp/*.log

The logs from /var/log/messages are the same as before. I'm not sure what more debugging info I can provide. But if this doesn't help, I'll just switch back to 1.21.0 and wait for the next release Thanks again for the awsome application.
