Almost had it working

[healy]

I have two remote cams feeding ZM 1.19.4 on a fedora core 2 system (athlon 2400 XP -256 mb ram) mjpeg stream (24 bit color 352X288) I could get:
one cam streaming - the other not streaming (only stills)
so used the faq increased shmmax to 134217728.
this gave me 2 streaming cams in montage view, as long as the window was open, close the montage window and one of the cams went to 0 fps, the other stays at around 4 fps but no stream showing or, when I reopen the montage view I got a message from apache (in the montage window) image cannot be shown because it contains invalid charecters. When opening the individual cam windows neither is showing a stream, just the broken image with one showing frame rate of 4fps the other 0.0fps and/ or the invalid character message, according to /var/log/messages though zm is still capturing (INF=0,debug=0) for both pid's.
I then shutdown zm + apache, restarted apache, changed the ring-buffers on both camera s to 50.
now I get the following (after starting ZM) message:
zmc: zm_image.h:192: void Image::CopyBuffer(const Image&): Assertion `width == image.width && height == image.height && colours == image.colours' failed.
'zmc -m 2' died at 04/06/30 02:09:34, signal 6
I am wondering if I need to tweak apache (correct me if I'm wrong) because most ZM processes run within apache and I'm running it as it came out of the package (completely stock) or is there something enterily different going on here?
Thanks in advance for any help cause I stumped
