ZoneMinder Forums

Zoneminder newbie here. Clean install of Debian 9.2 on an old PC. Clean install of ZM 1.30.4. Dual-core with 2 GB of RAM. 2 cameras, a low-res USB and a Foscam C2. Load is < .5, shm is about 44%.

In general things are mostly working. I can look at a live feed, motion detect works, I can look events.

But, there are lots of errors in my log, most related to the Foscam. Before trying to figure those out, I thought I'd start with something simple:
I tried to export the log so I could paste it here. That doesn't work either: I assume that is the same problem.

I've checked, /tmp/zm is owned by www-data:www-data, mode 755. All of the ZM process are running with uid mapping to www-data.
/tmp/zm is empty.
/tmp/zm is part of my root file system, which has about 300 GB free.

Suggestions?

Thanks much!

Debian uses private tmp folders so even though you can see the files & folders, zoneminder cannot because it is running under a different user account.

Go to Options -> Paths and then inspect each PATH_XXX variable. If it is set to "/tmp/zm", change it to "/dev/shm". Don't forget to restart zoneminder.

This is technically a packaging issue which should be reported to Debian bugs.

I have updated the Debian 9 WIKI instructions with this step:

I changed the value of PATH_SWAP from /tmp/zm to /dev/shm. This was the only path referencing /tmp.
This appears to have solved the problem.

Thanks!

If you want to leave PATH_SWAP as /tmp/zm ...

Another solution is to edit
/etc/systemd/system/multi-user.target.wants/apache2.service

and change
PrivateTmp=false

then restart systemd and related services or restart the computer.
