Modect crashes then reappears again and again

I am using a Trendnet ip-100w at 640X480 @5fps medium compression. I am able to use the camera intermittently and see the feed OK for short periods of time in Zoneminder using Fedora 13. I have been trying to follow different posts regarding shmmax and shmall settings as I was getting the dreaded "0x7a6d0002" error. I defined shmmax as below and let the system arrange shmall itself.

I managed to capture the instance when the screen goes black on Debug=9 so I hope there is enough there for someone to glean info. I came up frustrated after Googleing for a few days of playing around with shared memory settings.

The gold starts in the second block where zmu changes to zms
I just did a "head -10 /tmp/zm_debug.log.08883[3-7] to spare you the spam.

Let me know I need to supply more info. Thanks for your eyes and brains.

Try to lower down 'Stream Replay Image Buffer' to 100 instead of 1000. Post results.

Hi,

Please post debug log for zmc too.

Also, you might want to try using mmap mode. I believe its the default selection in 1.24.3 and in my opinion is superior because it usually just works out of the box, no need to fiddle with the shmall\shmax stuff.

I did this sort of. My original value was 2000 so I knocked off a zero and it seems to be working for the last two days.

Thanks!
