Ok, I will try this afternoon
On 1.34 I'm using same settings without issues.
memory leak in mocord
Re: memory leak in mocord
On 1.34 I'm using same settings without issues.

Re: memory leak in mocord
lowered frame analysis to 5 and slowly, after 1 hour, memory leak happened again
Production: zm 1.34.26 - Debian 11 | Test: zm 1.36.33 - Debian 12
I have identified the problem
I need the recording to be divided into 30 second sections because I have to post-analyze the videos that have alarmed frames. With this setting the memory filling problem occurs.
With the default parameters instead it seems that the system is stable but it is not suitable for my needs.
As I wrote earlier with version 1.34.X it doesn't happen

Re: memory leak in mocord
1.34 used a fixed length array to hold images. If it ran out it would log lots of errors but not consume ram.
1.36+ uses a non-fixed length queue. It is limited by MaxImageBuffers. It includes the encoded 264 data as well as decoded images so can use more ram than in 1.34. Again though, if you hit MaxImageBuffers packets in the queue, it will be logging all kinds of warnings and errors.
If you are running out of ram, ZM will be complaining about it bitterly. Go look in your logs.

"Found locked packet when trying to free up video packets. This basically means that decoding is not keeping up."
"You have set the max video packets in the queue to 45. The queue is full. Either Analysis is not keeping up or your camera's keyframe interval 16 is larger than this setting."
Is there anyone who can try to reproduce the anomaly by setting the parameters like me?

Re: memory leak in mocord
I didnt have any footage I cared to save so I went ahead and deleted and recreated the monitors, kind of inconvenient but now everything appears to be normal again, knock on wood, and has been for a little bit, i'm barely at 1.5 GB of RAM usage now. Hubspot partner agency

Re: memory leak in mocord
There is a memory leak in 1.36 and 1.37. It happens when zmc restarts on a failed rtsp connection. It looks like it releases some of the memory not all of it and each time it restarts its releases less memory. 1.36 takes longer than 1.37. I have 2 different systems that do the same thing.
CPU usage climbs as the memory is used up until it uses up the swap file and the server becomes unresponsive.
Here is the kernel dump info from zmc. This is on a clean install that was done last night on Ubuntu 22 with 1.36.33. The VM is configured with 8 CPU's and 16GB of memory. The only thing I took from the old system was the config.
This is the config for the camera that was offline. It is currently set to none but was set to modcord.

Re: memory leak in mocord
That's totally possible, and should be easy to recreate.
I have several very flakey cameras though, and I don't see that here... but then I give my machine a lot of ram.

Re: memory leak in mocord
Here is what htop is showing. Monitor 10 is a camera that is on wifi that bounces on and off. It has lots of sub processes while all the rest only have 5 total.
Re: memory leak in mocord
a monitor should only have about 5 threads. Maybe a couple more ffmpeg is using a threaded decoder.
A possibility is that it is taking too long to close events. We use a separate thread for each event to do the writing. Closing an event should kill off the thread.

maybe I fixed it
I think my problem was not related to bad network or bad rstp stream.
On my test environment I had only 1 SSD disk (SO, database, video storage etc.) and I thought it was enough for 2 cameras
The behavior changed after I added a dedicated disk (mechanical) for video storage.
Now the memory consumption has remained stable after 1 hour. I've added more cameras, let's see what happens in the next few hours.
For now, thank you all.
