Hi! All: I just finished installing v1.22.3 on my Fedora 9. Got some issues and need your help!

It seems when I add only one camera through the apache website,
everything works just fine. But after I added the 2nd camera, zmdc starts failing. It would work for a while for both cameras, sometimes a few seconds, sometimes up to 5 minutes, then both cameras crash and zmdc reboots. But, let me stress that if I delete one of the camera, everything works just fine. I am wondering if this has to do with the fact that I am running my fedora on a Pentium-III 800Mhz machine? Is it too slow?

Both cameras set tp 5 fps, 320x240 CPU loading varies from 10% to 80%. Here is a snapshot of /var/log/messages:

Looks like a buss error or a card detection problem.

What card?
What chipset on the motherboard?

If I had to guess I would say the card has not been detected, or maybe an IRQ conflict. Above commands should shed some light.

To be honest I forgot the model of the card. But here is the result of both commands:

I'd start by disabling anything in bios you don't need, free up some interrupts, sharing with the nic card usually always seems to cause problems but interesting is that it's the first two ports on your second card, are these the only cams on this card?

Thank you cordel. Sorry I forgot to mention. I have two cards installed. But only one of them are currently being used and there are 4 cameras hooked on to it. The first thing I would do when get home today is yanking the 2nd card out.

It's just so strange when I define only 1 camera, everything works smoothly. as soon as I added the 2nd camera, it start failing. The more cameras I add the more frequently zmdc would fail. for 2 cameras I am able to get a good 1~2 minutes of video before zmdc crash and restart, but for 4 cameras I only got a few seconds.

By upgrading to a new machine ...

The old one is really too old. P-III 800. And it has SCSI interface on it, make things a little bit too complex. I believe it has nothing to do with the software, some IRQ conflict maybe.
