[SOLVED] "Unable to capture image, retrying" after upgrading to 1.30.2

Hi everybody,
I just upgraded to 1.30.2. After this, Zoneminder can't receive the images from one of my three cams anymore. Two (both Instar cams) work fine, the third one (Axis) doesn't. In /var/log/syslog I can see a lot of entries like this:
Code: Select all
Feb 11 13:43:16 myzmserver zmwatch[3192]: INF [Restarting capture daemon for AxisCam01, time since last capture 27 seconds (1486816996-1486816969)]
Feb 11 13:43:16 myzmserver zmdc[3087]: INF ['zmc -m 6' starting at 17/02/11 13:43:16, pid = 7007]
Feb 11 13:43:16 myzmserver zmdc[7007]: INF ['zmc -m 6' started at 17/02/11 13:43:16]
Feb 11 13:43:16 myzmserver zmc_m6[7007]: INF [Starting Capture version 1.30.2]
Feb 11 13:43:16 myzmserver zmc_m6[7007]: WAR [Unable to capture image, retrying]
Feb 11 13:43:26 myzmserver zmwatch[3192]: INF [Restarting capture daemon for AxisCam01, time since last capture 10 seconds (1486817006-1486816996)]
Feb 11 13:43:26 myzmserver zmdc[3087]: INF ['zmc -m 6' sending stop to pid 7007 at 17/02/11 13:43:26]
Feb 11 13:43:26 myzmserver zmc_m6[7007]: INF [Got signal 15 (Terminated), exiting]
Feb 11 13:43:32 myzmserver zmdc[3087]: WAR ['zmc -m 6' has not stopped at 17/02/11 13:43:32. Sending KILL to pid 7007]
Feb 11 13:43:32 myzmserver zmdc[3087]: INF ['zmc -m 6' crashed, signal 8]
Re-activating the cam, restarting Zoneminder and restarting the whole machine didn't solve the problem.
Could you please help me debugging this?
Thanks a lot and many greets
Stephan

Will have to reload my test machines.
What Linux distro?

What Linux distro?
Ubuntu Server 14.04.5
Zoneminder repo:
Code: Select all
deb http://ppa.launchpad.net/iconnor/zoneminder/ubuntu trusty main
(is that "best practise"?)
Thanks and greets

Uh... I think we merged a "FIX" a long time ago that we will have to undo. I removed it from my dev branch a long time ago, but no one bothered to remove it from master.
For those following along, lines 195 and 196 in zm_remote_camera_http.cpp are bogus. They were put in to fix a problem with cameras that don't give a content-length header. But it breaks the logic and now zmc just spins waiting for more data and never parsing what it has.

thanks for identifying the problem so fast!
But... I'm just another system administrator, no clue about coding.
Is there anything I can do to fix my current installation?
Sorry for silly asking and greets

Hi,
is there anything I can do to bring the cam back to work?
Is it possible to downgrade to 1.30.0?
Thanks and greets

Not sure as the PPA had some issues, but I think they are resolved, you could try specifying the package version back to 1.30. Or you could use the package build script to build your own from master that has a fix. Or wait for iconnor to package master on the master spa, or wait for us to do RC2 that should have this fix included. I will raise the question of RC2 to see if we have enough changes to warrant it.

Hi Steve,
thanks for this overview!
I just downgraded the zoneminder package via
Code: Select all
# apt-get install zoneminder=1.30.0-trusty1
Cam is back, no issues so far!
Thanks and many greets
Stephan
