Solved. Alarm recording stopped

ludri · Post by **ludri** » Tue Jun 16, 2009 9:12 am

My setup was working fine until yesterday it does not store any alarm events.

My setup:
Ubuntu 8.10, ZM 1.24.1
P4 2.6, 882MB ram, kodicom 4400r running with 1 camera.

Camera is running at 384x288 10fps and 20fps alarm. PAL, video for linux 2, bgr24. modect.
Image Buffer Size 40, Warmup 10, Pre 20, Post 20

When I force alarm I can see in /var/log/messages:

Code: Select all

In /etc/sysctl.conf I have:
kernel.shmall = 225792
kernel.shmmax = 462422016

I tried change shared memory, Image Buffer Size, Warmup, Pre, Post settings. But I did not get alarm recording back.

Generates only these:
Id Name Time Secs Frames Score
34317 New Event 2009-06-16 12:03:28 0.00 null/null 0/0 X

Update:
Seems it didn't like 384x288. Runs fine on 320x240.
But weird it worked fine before at 384x288 res.

I've been using it at 384x288 for 2.5 years, without a problem...

Today it stopped recording at 320x240.
I created new Monitor with exact settings (same input etc.), disabled the problematic monitor.
Records fine.

I'll do clean install someday with mapped memory setting.

Is it possible to migrate events to clean install?

Problem cause was the ext3 32000 limit:

And the ZM_USE_DEEP_STORAGE was not set.

I solved this by upgrading ext3 to ext4 like so: http://blog.ejbca.org/2009/04/migrating ... ypted.html
