zmc crashes with some resolution

I've a spectra8 board, used with bbtv module.

If I use 352x288 24bit, it works.
If I use 640x480 gray, it works.
If I use 640x480 24bit, zmc crashes.

Any idea? tnx

hi,
you must lower the buffer ring size or increase the shared memory.
I use 768x576 24bit colour with buffer ring set to 30 or so...
yo can set the buffer ring size (or "Dimensione del Buffer Immagine (quante immagini)" if you use my translation, it_it) from the monitor setup, then buffers

see http://www.zoneminder.com/index.php?id= ... faq_faq=10
for details.

davide,

It still crashes with 30 images as buffer.. I lowered it to 20 and it works.
Thank you.. If I'll need more buffers, I'll change the shared memory (even If I've to understand how to do it with Gentoo).

Grazie

One thing to be aware of is that often just changing the buffers by itself will not delete the existing shared memory segment, you should restart ZM completely. Otherwise you can find that even though you have enough shared memory space available in your system it's still trying to squeeze it into whatever amount was grabbed the last time ZM ran.
