Increasing usage of RAM memory

[mendozaLt]

Zoneminder slowly eats my server memory... I have to restart it at least once a day to get back to sane memory usage. Is there anything i can do to stop it stealing RAM? If i would not restart it it would probably go to the point where server starts choke, lag and restart...

When i restart it:

After few hours:

Is it actually causing a problem? You say it might cause a problem. My 16GB system is currently running with 851MB free. It has been up 17 days.

Hi. It's well worth checking the FAQs if you haven't tried already https://zoneminder.readthedocs.io/en/stable/faq.html

It's currently 56 Gb (to be upgraded), and its not only to zm, there is a lot other guys, that would like to get some ram... And it only three cameras...

[Andyrh]

On my 6 camera system there is not much 'free' RAM, but there is plenty of available RAM.

@watcher:~$ free -m
total used free shared buff/cache available
Mem: 15912 10015 982 468 4914 5091
Swap: 4095 1995 2100

When i restart zm, i also have plenty of available, but few hours later zm occupies most of it...

Approx an hour ago, when i posted this question, it was:

Now:

Numbers are not scary YET, but with this speed, tomorrow morning i will have redline on my webmin memory gauge...

I should have mentioned that is after 17 days.

It’s what it does. Hopefully it’ll be fixed one day.

We need to narrow down what your monitors are doing. I have had other reports of this but no amount of valgrind has shed any light.

So what are they doing? ffmpeg type? modect, mocord, etc? camera passthrough or encoding? jpegs? Is there a large number of events during the time when the ram increases?

[mendozaLt]

Two monitors Modect, one Monitor (does not record).
I haven't changed anything much far from default...

[mendozaLt]

Not so much events... 45 - 50 per hour, and they are short...

[iconnor]

Okay you are writing jpegs... I had a case yesterday where a machine was not keeping up due to writing jpegs.

Are there warnings in your logs? Is the timestamp keeping up?

I'll set one of my cams to jpegs and see if I can reproduce it.

Which exactly log file should i check? But anyway, there is nothing much wrong in the logs... Just some of these:

I found a memleak and have fixed it. Do you want to update to my proposed ppa and test it?

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

Should get you a 1.36.21 version although packages are building now and I can't guarantee when they will be available.

[mendozaLt]

I would, i tried...
