i think the shared memory is ok assuming the shmall is pages and shmmax bytes

siduxbox:/tmp# cat /proc/sys/kernel/shmall 2097152
siduxbox:/tmp# cat /proc/sys/kernel/shmmax 33554432

any help would be appreciated

To see if I understand the problem correctly if you reboot the box it would work fine for a few hours and you would get this message?

no a couple of days ago, late i had zone minder zmd capture daemons
running (2) with no log errors it was like 3AM and the cameras were dark
i was working remotely via ssh as this is friends box. When i looked again
they were not working and throwing irq errors as per my previous post.
My gut feeling is this is a borderline irq problem related to the kernel and the
the bttv driver-- from what i have been able to find on the web this has occured before with 2.6.8 10 and later kernels it was working then it quit.
Most of what i found on the web was for other programs but the bttv error
message where the same as i was seeing with zm.

The box and hardware had been running zm
with an earlier kernel but the install had been trashed by someone who had no clue of what they were doing. I was in town for a meeting and as a favor put a fresh debian sid(sidux) and built zm 1.22.3 for him. Ran out of time and told him i would config it remotely on the condition he kept his hands out of the config file.

Have you seen this before? It is missing interupts and causing an overflow contition for frame sync buffer. I looked at cat /proc/interupts it is a four
chip card and two of the /dev/video# channels had an interupt to themselfs
i.e. were not sharing the interupt with anything. Could not get those to work either
thanks
