Hi folks...
I'm not that good in English....
I'm getting some errors on zm like "kernel time sync error 1" and several "WAR [Buffer overrun at index N, slow down capture, speed up analysis or increasse ring buffer size]
I've tried several kind of "help" here in the forum, but no one had no effect...
I would really like some help here...
Thanks...

What are your setting for:
Image Buffer Size (frames)
Warmup Frames
Pre Event Image Buffer
Post Event Image Buffer

Hi...
My settings are:
Image Buffer size (frames):50
Warmup Frames: 25
Pre Event Image Buffer:10
Post Event Image Buffer:10

Any ideas??
Thanks for the help!

You can try increasing the ring buffer and set Image Buffer size to 65 but I think some thing else is amiss. If you run dmesg are there any errors towards the end?

Posted: **Mon Feb 02, 2009 10:59 am**

No, dmesg returns no errors

Just for help, my CPU configurations are:
AMD Athlon 1.2 Ghz
40 GB Hard Drive
512 MB RAM
GeForce4 MX 4000
I have 7 cameras on it, soon it will be 8

It's an old machine...
Do you think that if I increase to 65 the buffer size will solve it?

Thanks for the help

Have you tried increasing the buffer or decreasing the capture speeds yet?

Posted: **Thu Feb 12, 2009 5:08 pm**

Hi, my settings are: Buffer Size:50 and Max FPS 2...So Pre and post event are still 10 and warm ups 25 and several Buffer overruns...I really don't know what to do...

Posted: **Tue Feb 17, 2009 1:40 pm**

I forgot to tell... the overruns are not the only problem... sometimes i have to restart the machine because the overrun problem... and when reboot it displays the error... "fsck died... on /dev/hdaN"... then I run "fsck /dev/hdaN" it's ok for a while... but sometimes when I reboot the linux this message appears... any ideas about this?

I'm having this exact problem, but I have 32 cameras running. I have increased the amount of shared memory (from 128 to 457MB), I increased the image buffer on all feeds to 60 from 40 and although I don't get as many, I still get some buffer overrun messages:

Code: Select all

Feb 18 05:05:56 camera zmc_dvideo11[9837]: WAR [Buffer overrun at index 44, slow down capture, speed up analysis or increase ring buffer size]

What other change can I make to give Zoneminder the amount of shared memory it needs for the 32 cameras?
