Shared Memory problems remain after following FAQ

[cdavis]

I have my NC1000 set to 640x480 and I still get:

Jun 24 12:13:23 localhost zmu[8745]: ERR [Can't shmget, probably not enough shared memory space free: Invalid argument]
Jun 24 12:13:23 localhost zms[8751]: ERR [Can't shmget, probably not enough shared memory space free: Invalid argument]


I have done the following to increase the shared memory:

echo 134217728 >/proc/sys/kernel/shmall && echo 134217728 >/proc/sys/kernel/shmmax

In FC4

If I change the resolution to 320x240 it seems to work fine. But I would sure like to take advantage of the camera as much as I can, or am I just not able to do 640x480?

Have you restarted zm after changing shared mem allocation

[cdavis]

Well I had thought so, but obviously not since that fixed it. Thanks. My proc usage went so high after that I had to take it back down anyway.

[jameswilson]

It shouldnt effect prec usage (not adjusting shared mem) unless you are short on ram. If you upped the resololution this would obvisouly increase proc usage

[cordel]

Actually his proc usage would increase because zm is actually able to now analyze images assuming the modetect or mocord are being used. You might try lowering your FPS.

lol i meant that using 320x240 and just increasing shared mem shouldnt increase the proc usage but if using 640x480 prox usage wouls increase. Quite a bit even at the same fps. I must learn to write things better so more people understand what i mean!

Yeah same here eh?
I will try to do a bit better. I am assuming that 640x480 was being used when he said it started working after restarting zm.
