The only Google hit for "Can't insert event: MySQL server has gone away" is this thread. ;) Searching for just "MySQL server has gone away" is much more productive. The suggestions are: 1) The connection has timed out. 2) mysqld has crashed. 3) mysqld has been re-started. I see t...

The replication configuration change hasn't stopped this intermittent crash from happening... intermittently. Curiously, yesterday morning it affected 3 out of 4 monitors, but not the fourth. Weird.

The only mysqld error that might be significant is one complaining about the lack of a --log-bin setting. It suggests this only applies to replication, which I'm not using, but I've now fixed it anyway, and I'll keep an eye out for other failures.

Well, the zma daemon definitely seems to re-start itself after one of these events...

I guess I should take a look at the zoneminder ebuild in portage, and see whether i can figure out how it might be fixed. Havn't yet got the hang of the new way of doing webapps though...

Definite oddness. What's the code around line 123 in your version of zoneminder say? In mine it's the "}" at the end of an if block... Ooops! Wrong version! The offending line says chdir( ZM_DIR_IMAGES ); which makes a lot more sense! Check that the .../images directory (and events, graph...

Definite oddness. What's the code around line 123 in your version of zoneminder say? In mine it's the "}" at the end of an if block... My gut feel is that you've not configured something basic, like a webserver-writable session directory, but that's pure guesswork. Did you emerge zoneminde...

I got a flurry of these this morning. MySQL seems to have kept running throughout. Mysqlcheck reports everything OK. Curiously three out of four monitors crashed but the fourth was fine.

Thanks folks. I'll let it upgrade and see what happens.

Oh boy... On Gentoo, mySQL 5.0.26 just went stable. I've had PHP 5 masked out for a while, but in theory PHP 5.1.6 is stable too. Looks like I'll have to bite the bullet and let them both through soon. Are there any known " gotchas " with zoneminder 1.22.2 and mySQL 5 and PHP 5, or does it...

This story from The Register might be worth a quick skim: Surveillance cameras outfitted with internet technology are open to tampering and interception, security experts warn. IP cameras, widely available from around £70 and not to be confused with web-cams that connect directly into PCs, connect i...

My guess is you'll need more memory, and the CPU(s) will be working quite hard, but both of those could be traded off by reducing the frame rate. The catch is that you need the shared buffer memory all the time, so you need enough non-shared memory left after the shared memory has been allocated for...

Another common problem with switching between IR and visible light is the way the focus shifts, so a camera that's nicely focused for one produces a slightly out of focus image for the other. :/

To mis-quote Scotty: "Ye canna change the Laws of Physics, Capt'n" ;) Anti-reflection coating is an expensive business, even assuming it's possible. Anything that dulls the reflection is likely to make the lighing even less effective. Your best bet is to get the LEDs to other side of the g...

Is there any way we can get finer grain resolution on this setting? No. It is by nature counted in whole frames. However, you should only need it set higher than 1 if: You are using a capture card that shares one capture chip between two or more inputs, and you are using a resolution greater than 3...
