I'm a ZM newbie. I'm passable with linux/unix.

I loved playing with it a few weeks ago when I tried my first download.

Now, I'm getting ready to deploy a version for real life use. So far, I haven't found anything that just works. I'm not adverse to fiddling, if I get something at the other end that is robust. I feel like every time I fiddle with ZM, something else is a breaks.

I just did a fresh install of 1.36.8 on Ubuntu sever focal. I followed exactly:

https://bkjaya.wordpress.com/2021/05/15 ... cal-fossa/

And there are memory problems and:

10/15/2021 13:14:20.053439 zmdc[1282].INF [ZMServer:411] ['zmc -m 1' starting at 21/10/15 13:14:20, pid = 3953]
10/15/2021 13:14:20.053449 zmdc[3953].INF [ZMServer:411] ['zmc -m 1' started at 21/10/15 13:14:20]
10/15/2021 13:15:03.844450 zmdc[1282].INF [ZMServer:706] ['zmc -m 1' crashed, signal 8]

Events fail after one second.

I tried to follow:

but the mods to the mysql conf were fatal in my case and I'm not good enough at mysql to run down the problems

Is there an install of a recent version of ZM (preferable 1.36) that's pretty bulletproof?

Drop out the database tweaks and then work through any remaining problems. It’s might not be 100% plug and play, but it’s not bad.

The instructions for 1.36 havn't changed since 1.34.

Just type 1.36 instead of 1.34 wherever appropriate.

Easy instructions: https://wiki.zoneminder.com/Ubuntu_Serv ... der_1.36.x

I am having the exact same problem and been pulling my hair out lately. Constant in the logs.

Any ideas?

There are errors in that guide which will very probably stop MySQL/Mariadb from starting: innodb_buffer_pool_ size shouldn't have a space in it, and innodb_log_file_size - 32M should be innodb_log_file_size = 32M (equals instead of minus)

Also, changing innodb_log_file_size can often prevent the service starting or the InnoDB handler/driver loading if you don't get rid of the old logs first.

Check the database log (/var/log/mariadb/mariadb.log) for errors along the lines of You can probably fix this (works for me) by:

Stopping the mariadb service (systemctl stop mariadb).
Deleting (or moving/renaming) the old log files (mv /var/lib/mysql/ib_logfile[01] /tmp/)
Starting mariadb (systemctl start mariadb)

Check the log again and you should see a warning that the log files are missing and that they're being recreated.
