[Config Support]: Regular spikes in CPU/Network Usage #20644

Describe the problem you are having

I have a fairly regular issue with Frigate's CPU utilization gradually increasing and staying high until it either drops again on its own or (more frequently) until I restart it. I'm running Frigate on Proxmox (I know, I know...) in a docker container in a LXC on an i7 NUC with Coral TPU.

See the graph below where the utilization went gradually up last evening and only dropped when I noticed it in the morning and restarted Frigate. The same thing is gradually happening again right now:

Interestingly enough I can see the same pattern in the container's network usage which effectively doubles:

However when I look at the traffic on the camera ports, it's what I would expect it to be and only adds up to about 50Mb/s, consistent with the baseline of 5MB/s shown in the Proxmox graph:

I can also see the same spike in the network (but not CPU) utilization of my HA VM, running on the same Proxmox instance - I have the Official Frigate Proxy addon running in HA, using the official integration.

Restarting HA (which I just did at 22:45) also temporarily restores the network traffic (and Frigate's CPU utilization) back to the baseline level but then it immediately creeps up again and only really goes down for a longer period of time when I restart Frigate (23:04)

HA VM Network:

Frigate's LXC network:

I'm attaching my Frigate config and logs, you'll notice I'm also struggling with ffmpeg errors - I've tried some Gemini suggesting for addressing those (marked with #gemini) in the yaml however I've reverted those as I haven't really seen a meaningful difference and while I'm still trying to address this issue first.

Happy to provide any other info that may help resolve this.. thanks!

Based on your symptoms and configuration, here are several potential causes for the gradual CPU and network usage increases:

Configuration Issues

1. Birdseye Continuous Mode

Your config has birdseye.mode: continuous which keeps Birdseye constantly running(1). This creates additional processing overhead. Consider switching to objects mode which only activates when objects are detected.

2. Multiple Audio Streams

You're running audio detection on three cameras simultaneously (entry_camera, gate_camera, street_camera)(1). Each audio stream spawns a separate ffmpeg process that continuously processes audio, which adds to CPU load.

3. Semantic Search and GenAI

You have both semantic search and GenAI enabled(1). The embeddings manager (showing 234ms image embedding speed in your stats) processes frames for semantic search, which adds CPU overhead. Consider disabling these features temporarily to see if they're contributing to the issue.

Proxmox-Specific Considerations

Running Frigate in an LXC on Proxmox is not officially supported and can introduce complexity(2). The documentation specifically notes that "Running Frigate in a VM on top of Proxmox, ESXi, Virtualbox, etc. is not recommended"(2). However, some users have had success with proper configuration.

For your LXC setup, ensure you have proper device passthrough configured:

For Intel hardware acceleration: lxc.cgroup2.devices.allow: c 226:128 rwm and lxc.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file(2)
The LXC should have features: fuse=1,nesting=1(2)

Memory and Storage Issues

Your stats show /dev/shm is using 570.7MB of 1024MB (55%)(3). When the system is under stress, this could fill up. The documentation states that /dev/shm is used for "internal cache for raw decoded frames in shared memory" and "it is not recommended to modify this directory"(2).

Consider increasing your shm_size from 1GB to match the calculation: you need enough space for decoded frames. With 7 active cameras at 1280x720, you may need more than 1GB(2).

Recommendations

Disable features temporarily to isolate the issue:
- Set birdseye.enabled: false
- Disable audio on all cameras
- Set semantic_search.enabled: false
- Set genai.enabled: false
Monitor go2rtc - Your go2rtc logs show multiple timeout errors and broken pipe messages(1). This suggests connection issues between go2rtc and your cameras or between Frigate and go2rtc.
Check for recording issues - Enable debug logging for the recording maintainer to see if slow disk writes are causing backups(3):

logger:
  logs:
    frigate.record.maintainer: debug

(3)

Review your tmpfs cache - Your /tmp/cache is set to 2GB which should be adequate, but monitor if segments are backing up there during high load periods(3).

The pattern you're seeing (gradual increase until restart) suggests a resource leak or accumulation issue, possibly related to go2rtc stream handling, audio processing, or the embeddings/GenAI features running continuously.

Dropping in to say you are not alone. I have the same issue here where every 7-8 hours CPU spikes and stays 100% for ~1.5 hours and have been searching for a resolution for months. This user on Reddit also has the same issue https://www.reddit.com/r/frigate_nvr/comments/1lofmi9/high_cpu_load_after_a_while_no_interaction/.

Do you also see utilization/network spikes on HA side at the same time? I have applied the changes suggested by inkeep and I have not had the issue in a couple days now, I'm slowly restoring everything I've disabled to see if it comes back because I still don't think it's deterministic.. I have also noticed a weird behavior of the birdseye camera entity in HA (rapidly changing status) so i've disabled it and the re-enabled and it seems to have stabilized.
