I didn't change any settings, but suddenly events stopped being
recognized and recorded!
On both cameras!
Please help.
Alex

Hi Alex,
Sorry but we're going to need alot more information. Please check your logs and snip anything that looks related. Also an idea of your setup ( Please see Sticky: PLEASE READ BEFORE POSTING!!!)
Cheers,
Cordel

I looked at /var/log/zm but couldn't find anything related to the problem.
Its a setup with 4 - channel dvr card.
I have a perfect video on at least 2 channels, but its not generating events any more.
Which logs should I look at?
Alex

Check your filesystem still has space.
Check /var/log/messages (or syslog, daemon.log, kern.log, or wherever).
Check wherever you've put the zm log files.
Check the zm web-console...

Checked /var/log/messages!

Jun 28 13:44:`3 zoneminder zmc_d0[5196:
:WAR [Buffer overrun at index 17]
This can be the problem..?
Alex

Can it be the memory issue?
Currently I have 128 Meg running Fedora core3.
Alex

They're both possibilities, but it's hard to guess from the information you've given. I suspect the overrun suggests that your (shared-memory) buffers aren't quite large enough.

Presumably you've tried stopping and re-starting the zoneminder daemons?

Which zoneminder processes are running? (Try "ps auxw | grep zm" as a quick check. Also, using the "top" command might tell you something.) What's your memory usage like? ("top" will tell you). You have checked that there's space in your file systems (use "df -k" or similar).

I think there should be one zmc process for each video device, one zma process for each monitor, and one each of zmfilter.pl, zmaudit.pl, zmwatch.pl, zmtrigger.pl, and a perl process running zmdc.pl.

Alex, You might try a full reboot if you haven't already just in case something has the memory tied up. But try what lazy said and post the results first.

Buy more memory! I am doing B/W 358x288 pixels at 20 fps and I can barely manage with a 1 GHz Athlon and 512 Mb of RAM.

I dhecked processes for Zm.

I tried rebooting - but problem syill remains.
Will get more memory today.
Regards, Alex

Another misfortune:
When tried to delete events, got an error:
Incorrect key file for table:'Events". Try to repair it.
May be this is the part of the problem?
Alex

Hi Alex,
Sounds like you may need to repair your database. The database might get corrupted if the machine loses power or anything that would not allow services to properly shutdown or disconnect from the database.
try running this.
mysqlcheck --all-databases --auto-repair -u root -p
