Zoneminder stops capturing for a moment, then starts again

[adamwenner]

hey, i have 2 axis 2100 network cams connected to a switch that also contains the Zoneminder server. I have the cameras set on 5 fps to cut down on bandwidth because of other things running on this server.

Zoneminder seems to be capturing frames from the cameras fine, but every minute or so, it stops and the IP addresses in the web interface turn red, then they come back on in a few seconds, it is not necessarally both cameras at the same time, but sometimes it is, leaving a ~10 second gap in motion detection, which is unacceptable

is there any fix for this or does anyone know anything that would be causing this.

its not network bandwidth or CPU or RAM For that matter.

logs dont say anything from what i can find

let me know if you need any more information

thanks

If the cameras are going red then that would imply that they are crashing or being restarted. You should be able to check this by looking at zmdc.log or /var/log/messages. If you can verify this and report what you see then we can move onto the next step which is to find out why it's happening!

heres what i got in the zmdc.log

(this one was particularally bad, both cameras died)

the cameras are responding fine from what i can tell, it is something with zoneminder, unless as shown there, the cameras are putting out 2 SOI markers (no clue what that is)

What cameras do you have?

Assuming you have built with libpcre.a you can try fiddling with Options->Network->ZM_NETCAM_REGEXPS to see if that makes a difference.
