Released 1.36.30,31 The Memory Remains

[iconnor]

#Changes since 1.36.29

- Test for definition of ZM_LOG_INJECT. We don't include the config when not logged in. So it won't be defined and an error will be logged
- Fix saving from the function modal (and other modals)
- left align option value column
- when a config value is overridden via *.conf files, put up a warning/explanation on the options view
- Turn failure to send into a debug instead of warn. When running under fpm etc we may not get SIGPIPE.
- Move relevant code out of includes/actions/auth.php into includes/auth.php. Fixes inability to login using GET method.
- Don't panic if no font file found. We seem to be able to continue without it.
- Rework session handling to fix breakage with php8.2. Please note that php 8.2 still completely breaks a ton of our code. Do not upgrade to php8.2 and expect ZoneMinder to work.

# Changes since 1.36.30

- Fix failed login due to remoteAddr not being populated in session after regeneration
- Use REQUEST instead of SESSION to store the post login redirect because we clear the session on login. Fixes #3517
- Turn off logging of deprecation notices so that we work with php8.2

On 1.36.29, and now on 1.36.31, I am seeing zmc out of memory errors.

I have noticed that after update of 30/31 that my /dev/shm is growing and sometimes quickly. Prior, to 1.36.30 it was steady at about 22%-24%, Yesterday it hit 100% and zm started crashing . a restart of zm cleard this out and the /dev/shm is now at 20%. Here is what I found. Many entries in the /dev/shm that say "deleted" but must still be there? Using the lsof /dev/shm shows:

sudo lsof /dev/shm

There where very minimal changes to the c++ code between 1.36.29 and 1.36.31. It was all mostly on the php side. So I don't know what's going on.

You will have to turn on debugging and look at the logs.

The 100% shm is interesting. Yes being out of shm will cause crashing, but what's with all the deleted mmaps? Do you have zombie's?

Logs.

[Solved] I ran:

sudo apt install php8.1-intl

systemctl restart apache2

[Explanation] I had been using php 7.4 and thought I had upgraded to php 8.1 - possible there were conflicting php entries which manifested on the restart.

Some background: I have 3 Wyze v3 cams all in use a several months ago; two of which are using the mini-hacks from GitHub; id# 2 and id#7; the third is using rstp firmware from Wyze and is working fine; the other two are the problem now....so I suspect that this wyze mini-hack firmware may be the issued.
I was not sure what debug level to choose, so I selected level 3; and component _zm_m2 which is the main problem. After I started the debug and soon after, my log started getting the following; hundreds of these:

So I turned logging off and I do have some logs; size from up to 400mb. too much logging?

[iconnor]

So the question is did these work before 1.36.30? Cuz I really havn't changed anything on the c++ side in while.

Those errors tell me that ffmpeg doesn't like the stream, maybe not enough cpu or too many dropped packets.

[tinymouse]

I should have checked this first; Think I found the issue. If you noticed all the dead zombie tasks they all have the the same PID. When I did a lookup of the that PID, turns out to be a different monitor....sort of.. below is a small list, you'll see pid 87536 with /dev/shm/zm.mmap.7 (deleted) AND with /dev/shm/zm.mmap.4. So I think this has something to do with linked monitors. I have disabled the linked monitors and re-started them. I'll watch and see.

zmc -4 is a LINKED monitor to zmc -7 (true for my zmc -3 linked to zmc -2)

EDIT: This just happened to coincide when I upgraded to 1.36.30/31 and did a couple of linked monitors, so it may have nothing to do with this update....just fyi

[boris.yordanov]

Now at 1.36.31 (on Ubuntu 20.04.5 LTS) and cannot delete zones (at least this is what I've found, yet). Whenever i try to delete a zone I get this log entry:

Code: Select all

web_php		1975271	ERR	actions can no longer be performed without POST.	/usr/share/zoneminder/www/index.php

Any ideas how to work around it?

[iconnor]

add my proposed ppa to get the 1.36.32 pre-release.

sudo add-apt-repository ppa:iconnor/zoneminder-proposed
sudo apt-get install zoneminder

[boris.yordanov]

Yup, fixed. Thank you.

[bbunge]

Ubuntu 22.10 install fails with unmet dependencies: needs libswscale4 or 5 and libswresample2 or 3

libswscale6 and libswresample4 are available in 22.10

[iconnor]

Thanks for the heads up. Will be supported in 1.36.32.

I have this issue too, but am running a docker instance so adding the `proposed` ppa is not quite so easy.
Is there a workaround I can do using a POST command via curl? I see the url that is attempted via the browser url bar, which looks to contain the commands needed:

Code: Select all

http://192.168.220.11/index.php?view=zones&action=delete&mids%5B%5D=2&markZids%5B%5D=6&deleteBtn=Delete

can this be reformatted into a curl POST with appropriate --data parameters to achieve what I want to do?

[iconnor]

Edit the zones view and change the method="get" to method="post" in the form tag.
