I have already read a lot of posts about shared memory problems, i changed the values of SHMMAX and SHMALL. I changed from Debian Lenny to Fedora 11, i have put the D-link cameras in the lower resolution posible and in 8 bit color, I put the buffers on low values. But they keep going randomly to black after a few seconds of starting the server.

Any comment will be really appreciated.

Thank you in advanced.

I can't offer any solution, but I have the same problems. Fedora 10 was working fine, so I think it's an OS problem. But I kept all my settings and reapplied them. No luck.
I'm going to burn down Fedora and try CentOS 5.
