Can't get shared memory id '7a6d0001 error in SUSE 11.0

[igman]

I installed 1.23 using Yast in SuSe 11.0.

Install went fine. I can access web page ,
I can configure monitor. I have issue when I start to watch monitor. Web page froze up and ZMC and ZM service get frozen as well. I can not sopt Zm service.

This is what I have in ZMwatch

When i run
cat /proc/sys/kernel/shmall
I am getting
134217728

cat /proc/sys/kernel/shmmax
I am getting
134217728

I did search all forums and try increasing or decreasing memory setings with no success.
I am running 2 Ghz Pentium with 2 GB of ram and ATI TV wonder card. Eveything worked fine in SUSE 10.2 and with 1.22 version.

I am dying for somebody to help me with this.

Same problem on suse 11 and fedora 9
I believe its a kernel bug. Just waiting for the later kernels.

Hello,

As far as I know v4l support was broken in the early versions of 2.6.25 but got fixed later. Sadly the kernel version of opensuse is a bit too old so that the bug still exist. As a solution you can try to update the kernel or wait till this is fixed.

Keep in mind that firefox 3 has also an issue with zoneminder http://www.zoneminder.com/forums/viewtopic.php?t=11775

hope this help

[kevin_robson]

Yeah, I'm taking the waiting option. I have both distros installed and ready and waiting for suse or fedora to release a patch. I dont want to use a custom kernel.

[kevin_robson]

Actually I've just checked the fedora update mirror and it looks like that is now version 2.6.25.9, with the problem being fixed in 2.6.25.7

Will have a go with that when I get a moment.

Wont help you with suse directly, but at least we will know that this was the problem.

[kevin_robson]

It seems to work on Fedora 9 now after the latest update of the kernel. Not fully tested it, but got further than before.

Just a case of waiting for the kernel update on suse 11 now.

[monex]

Today a new kernel was released for opensuse 11.0 (2.6.25.9) which should fix the problems

[kevin_robson]

Thanks for letting me know. Will give it a try when I get around to it.

[kevin_robson]

I can confirm Suse 11 now seems OK too.

Kevin:

Did you have to downgrade to FireFox 2 from 3?

Thanks,

ck

[kevin_robson]

No I'm just avoiding using that from the linux box for now.
Somebody suggested a firefox clone on another thread that I downloaded last night and that seems to work OK.
The name escapes me but you'll find it if you go through the last couple of pages of posts.

At least in Ubuntu, it's possible to install Firefox 2 in addition to Firefox 3. They'll show up as "Firefox 2 Web Browser" and "Firefox Web Browser" (3) in your applications menu.

I too can confirm the kernel update corrected the video bug. Installed 1.23.3 with OpenSuse 11.0. Also uninstalled Firefox 3.0; downgrading to 2.6. Works like a charm, and performance seems to be better.

To confirm: your problem with shared memory was resolved with a kernel update?

[kevin_robson]

Yeah, it works on suse 11.0 and 11.1 after an update.
