ZoneMinder Forums

Hi,
First i'd like to say thanks to the Author for a great program, but i am having a few issues getting everything working correctly.

Firstly, my system is an Athlon 64 X2 5000 with 1 gb of ram, and i'm running CentOS 5.2.

I have 2x Logitech QuickCam S7500 cameras that use the uvc_video driver and mjpeg_streamer.

Then i have a single Logitech QuickCam Go, that uses the gspca driver.

I have svn'd the latest code for both.

ZoneMinder is at 1.23.3 and i am using the default settings for buffers, image size for all 3 cameras is set at 640x480 at 5 fps.

Currently all monitors are set at modect

mjpeg-streamer is streaming at 5 fps also.

When i first boot the computer, everything works great but over time things slow down and i seem to get a bit of lag or delay between motion and when it appears in the monitor. The longer i go, the worse the lag seems to get and eventually either all cameras stop working, and show as red in the ZoneMinder console, or the server just crashes and i have to reboot it.

Does the machine not have enough ram, or perhaps i'm trying to stream the video too fast, buffers not big enough, etc.

I see no errors in the log that relate to buffer overruns or anything that looks like an error.

anybody have any clues as to how to fix this ?

Thanks.

Don't Leave the browser open on the server would be my first guess, sounds like your running out of memory.

I had considered that the box does not have enough ram, as some people on this forum have mentioned servers with 4 gigs of ram.

I have ordered some more ram that will bring the machine to 2 gigs of ram, but it's a stand alone server that does nothing else and i'm not running an X display on it.

I will try reducing the fps further and see if that makes a difference.

Just don't use a browser to watch the streams on the server and it will be fine.
Use another machine for watching streams.
It will not matter how much memory you have if you use a browser installed on the server, the browser will eat it all up.
