Hi,
I'm also experiencing this issue. Like a few others on the thread, my setup is a Pi 3B+ with the official 7" DSI display and a Hifiberry AMP2. I boot the system from a USB flash drive (sandisk ultra fit 16BG).
Here's the initial log after boot:

I've no idea if these are red herrings, but I have set the display to sleep after 10 seconds, and wake on play. The pixel aspect ratio is set to square.
I'm more than happy to share other logs/settings info if that would be useful.
Cheers,

Sigh.
Even though the title of this thread clearly says "with HDMI" it seems to have mutated into an issue with DSI displays.
My official RPi 7" DSI touchscreen is encased with an RPi that drives an external USB DAC. With no release of moOde has this system experienced the reported local display failure mode. I've seen it occur only with HDMI displays.
What I find interesting about the me-too DSI posts to this thread is that Alaini93 is using a HiFiBerry DAC+ Pro while pgzh1, ciro73, and new_bloke are using a HiFiBerry AMP2 DAC. Is it just a coincidence that these few DSI failure reports involve I2S and the same driver or are we seeing real evidence here? [I'm beginning to feel like an epidemiologist here.]
I'm not going to pull my encased system apart to test with an I2S DAC.
Perhaps one of you four who report experiencing the failure using a DSI display could try switching to a different audio output---onboard audio jack or USB DAC---and seeing if the local display function continues to result in the chromium-browser eating up system memory.
Regards,
Kent

I'm sorry that my post has irritated you. I'd be happy to delete it and start a new thread if you'd prefer. I test software for a living, and it's often the case that what looks like a specific scenario may have a root cause that manifests via other routes as well. I'd be more than happy to help investigate if it can be of use to the community of moode users. I have purchased a separate USB thumb drive for this purpose so I can switch between versions without a reinstall. Please let me know what information would be most useful in terms of output (other settings or logs).

Re "irritation": Sorry, I was feeling more bemused than irritated. There may well be a root cause but posts should not get buried in pre-existing threads before it's known if there is a connection.
IMO its better to have multiple threads with specific titles that later get merged when more details are discovered. This makes it much easier for readers and testers to find relevant conversations. If you've tried the forum search feature you'll know what I mean.
Still, I'm a curmudgeon channeling my college librarian on this issue (her motto: a place for everything and everything in its place). This forum is as messily organized as most other forums are. It certainly beats the old days when all things "moOde" were posted to a single thread on the diyaudio.com forum.
Re: more info
1) I've seen no similar posts from users of DSI displays and DACs other than HiFiBerry Hats. If there are such folks having similar problems, we need to hear from them.
2) I've already suggested a test which could show whether the coincidence of HiFiBerry Hats/drivers is a red herring.
Other than that, for either display subsystem we need some way of understand what's driving the chromium-browser's render process to binge feed on system memory. The usual Linux logs and tools suffice to tell us which process it is but that's about it. So far, we haven't found a way to characterize this with enough supporting detail to make an intelligent case to the chromium devs and/or the Raspberry Pi OS devs (or even which group to approach).
All suggestions welcome.

Kent

Hi,
As suggested, I tried setting the audio output to the onboard jack - the same issue was observed as before:

Is there any mileage in attaching chrome dev tools to see what's going on? I found a couple of hints on how to do that, but would need to set an additional flag when the local display browser is started - can you point me in the direction of where that's done?

OK, so the coincidence was a red herring. Not surprising, but a test is better than a guess.
As for running the local browser, have a look at /home/pi/.xinitrc
The last line launches the main chromium-browser process which spawns others.
Incidentally, /proc/<pid>/status contains lots of interesting info about a process. You can find the pid for the chromium-browser with ' type=renderer' by running ' ps aux|grep type=renderer'
Example:
Here the renderer process has pid=20035
Code: pi@710LD:~ $ ps aux|grep type=renderer
pi 20035 10.1 20.4 608876 193644 ? Sl Apr07 1368:53 /usr/lib/chromium-browser/chromium-browser-v7 --type=renderer --field-trial-handle=15160034476641370332,6248687004281252584,131072 --enable-features=OverlayScrollbar --lang=en-GB --enable-auto-reload --origin-trial-disabled-features=MeasureMemory --num-raster-threads=2 --enable-main-frame-before-activation --renderer-client-id=6 --no-v8-untrusted-code-mitigations --shared-files=v8_snapshot_data:100

On my Linux desktop and laptops, the main chromium-browser process spawns many processes of type=renderer, more than a dozen even with just a single tab, but we're getting only one in moOde. I've never bothered to figure out why the difference.

Well, here is one of my experiences.
I use a Pi-3B, without any display, local mpd-library with approx. 1000 records and 8000 titles.
Whenever the usage of the input cache in the mdp settings is enabled and in the play-queue there are local titles i.e. titles that are in the mpd database, moode becomes unresponsive. I don't know whether this has something todo with the problem we are discussing here, but I thought it is worth checking the settings of mdp to see if it makes any change.

@ duke.g
Definitely a different issue which deserves its own thread where those with experience using the input cache feature can advise.

I have been able to successfully connect chrome dev tools to the instance running on the pi by adding the flag:
Code: --remote-debugging-port=9222
to the command in .xinitrc that launches the browser. I then opened an ssh tunnel to that port:
Code: ssh -L 9222:localhost:9222 user@host
I was then able to open the devtools on my local machine:
If this provides some useful information, I'd be happy to dig further, but I might need a bit of guidance as to where to look (nothing obvious leapt out so far.)
Cheers,

Hi
first time contributor to the forum, loving Moode since early 2020 .
I have a raspberry Pi 3B with an Hifiberry DAC + Pro and an Osoyoo 3.5" DSI touch screen and with Moode 7.1.0 installed
I verified a similar problem with Chromium memory usage increasing until freezing Moode completely. This started to happen since, at least, version 7.0.1 (although looking retrospectively I had previously several Chromium Aw! Snap Windows the could be from a similar problem). The problem occurs typically around 27 minutes after pausing the music player.
Trying to avoid being a "Me too!" I used the Local UI display with HDMI on , and with HDMI off while using the DSI display . Independently of the HDMI it always resulted in the system becoming completely frozen after some time.
Although not proficient in Linux , I think I found a work around to prevent the problem to occur. I edited the file .xinitrc and added at the end of the chromium-browser launch line:
--single-process --no-zygote --no-sandbox
It is now paused for more than 1 hour without any signs of increase in memory usage (with htop showing memory usage to vary between 236 and 259 Mb).
PS: I do not know why it works but I realized using top that the Chromium process that was using the memory had a "type=zygote" and tried to follow from there.
