Shared data not initialised by capture daemon

[ThomasNovin]

I think this is a new problem for me, and it does not look like the old classic problem with too low settings on shared memory, found in FAQ etc?

Interesting observation, this only happens when I'm logged into the web gui. During the night there has been no shared data errors but there has been successfully recorded events.

Some log after logging in

Seeing exactly the same the same thing.

I recently upgrade to Ubuntu 14.04 and so moved to iconnor's (very useful, thanks ) zoneminder-master PPA. This flags the Zoneminder version as v1.27.99.0, but I guess that's just a placeholder

Same cameras setup in the same way using ffmpeg (libvlc returns a stack of errors) as I had with my 1.27 install on Ubuntu 12.04.

Everything OK except when viewing in the web view, where I get the same warnings and errors as posted earlier:

I opened an issue on GitHub but it hasn't lead to anything

https://github.com/ZoneMinder/ZoneMinder/issues/507

[c128]

Just looked at the comments on the Github issue, especially:

This is actually a warning. It is just telling you that the camera is not recording. It means that the zmc process is not running. You need to look into why zmc is not running. So check in the zmc logs. /var/log/zm/zmc*

I also had no output in my zmc_* logs, even with debug output on to the component files. However...the zmc processes for my 3 cameras *were* actually running, and didn't stop/restart over getting the warning:

Code: Select all

Switching on the LOG_DEBUG stuff further down the logging page - lots of verbose output in the /tmp/zm stored files, and I also start getting stuff in the /var/log/zm/zmc*.log files. However - it looks normal? Here's the output form a single quick session viewing in the UI:

However, within the zms log over this time, I have again:

[c128]

I ought to add that, in my case (and not the OP's) the "WAR-zm_monitor.cpp/424 [Shared data not initialised by capture daemon, some query functions may not be available or produce invalid results]" warning *seems* to be benign.

I can view live streams and recordings seem to be fine, but although my shared memory settings seem valid, I get the warning.

[daedalus]

any luck in finding a solution for this warning?
I have a slightly different issue - when i log in the gui and click on a monitor for live streaming the recording stops. When i close the live window the recording resumes.
