I am using Debian Squeeze (32 bit). I am using Zoneminder 1.24.2 because that is the most up to date version available from the debian squeeze repositories. I have two machines: A) A dual core Acer netbook (AO751h, 1G ram). B) An older single core Sony laptop (PCG-GRS615SP). Both have the same OS and the same zoneminder versions installed. I believe they are both configured the same. Everything works fine on the Acer, but I would much prefer to use the older Sony.
I have 2x USB webcams:
Bus 002 Device 003: ID 046d:080f Logitech, Inc. Webcam C120 Bus 002 Device 002: ID 046d:080f Logitech, Inc. Webcam C120
Both cameras are configured as Monitor, PAL, YUYV, 352x288 on both machines. I just physically swap the USB webcams between the two machines and restart zoneminder each time I want to try the migration.
The shared memory is configured the same on both machines
------ Shared Memory Limits -------- max number of segments = 4096 max seg size (kbytes) = 163840 max total shared memory (kbytes) = 671088640 min seg size (bytes) = 1
Everything works as it should on the Acer. On the Sony, I get this from the log files after turning debug on:

from both cameras, everytime!
xawtv works fine with both cameras on both machines.
I'm puzzled as to why the same version of zoneminder on the same version of OS should work OK on the Acer, but not on the Sony.
But all I really want is to be able to get it working on the older Sony. I like debian, but I'm not hung up on it and would be happy to try another distro, but it needs to be fairly lightweight as it is a rather old laptop.
Anyone got any suggestions as to how I may a) Fix the problem, or diagnose it further. b) Get a later version of zoneminder working on debian squeeze. Thanks
