Now that I'm all googled out and a million and one tinkerings have proven fruitless, my last resort is to consult you directly because I feel I'm all out of idea's now.
- ZoneMinder Version: v1.24.4
- Linux server 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:34:47 UTC 2011 i686 i686 i386 GNU/Linux
I have 5 IP Camera's. Identical D-Link DCS-920's (Firmware 1.04) 1 connected via cable and 4 connected via wi-fi. For the most part, everything is working except that I keep getting the same error messages in my /var/log/syslog (see below)
To aid in troubleshooting, I have now disabled all camera's except one. To eliminate wi-fi I am troubleshooting with the camera connected directly to the router via cable. (I have a Linksys WRT54GL Running Tomato 1.28.)
I've tried all kinds of things from tweaking the shared memory settings as per the wiki as well as installing the turbo libjpeg. I've tried various buffer settings and even tweaked QOS on my router to allow packets from the camera's through ahead of anything else. (I've also tried with QOS disabled, no impact on the results.)
Camera's are set to deliver 320x240 images at 5fps. ZoneMinder is set to the same. While set to Monitor, the only visible problem aside from the logs is that fps occasionally drops very low, like 1fps and I get a blue screen for a few frames every so often.
The machine running ZoneMinder is DEDICATED to the task and not running anything besides what's required. Apache, Mysql etc. It's a 3.06 GHZ core2 Duo with 2GB of RAM and CPU utilization rarely exceeds 30%.
I don't understand what could be causing the "Interrupted System Call" ERR because it's certainly not load related.
I hope someone with more experience with ZoneMinder will be able to point me in the right direction to get this solved. If there is any additional information I could provide that would aid you, don't hesitate to ask.
Here follows some output from tail -f syslog | grep zm:
