I’ve had music assistant installed for awhile and keep it up to date. I’ve been suspecting a memory leak for some time, but after seeing the memory drop after a restart (and update), I thought I would ask around. Looking at the last week of data, it doesn’t act like a leak…just high usage. I have a large collection(20K+ files). Is it just an artifact of that?
This is a 1 week time period. It seems to be between 3.8 and 4.7 during that period, with the amount going down towards the end of that period.
While I have it installed and indexing, I really haven’t been using it. I have my own song queue manager, but am following along with music assistant in hopes that one day I won’t have to manage my own custom code.
I haven’t monitored everything as meticulous as you but I can tell my Music Assistant had a big leak as it seems right now. My journey so far:
My system started to freeze up once in a while after I installed MA. I scheduled an automatic reboot to free up memory because I couldn’t find the problem. That kept it in check for a while. Untill the usb of the Pi stopped working so I had to replace it the Pi. It’s a Pi 4 with a powered USB hub for my SSD and Zigbee dongle.
It didn’t feel right so I uninstalled MA and my memory is stable again. Here’s my memory usage before and after the uninstall (12 o clock)
The leak comes and goes. I suspect it is related to indexing cycles, but I don’t have a lot of evidence. I may just restart the docker container on a regular basis.
I have identifed that MA is the culprit - I could watch the system memory be consumed and the memory percentage MA reported was increasing every time I refreshed the screen. This was without any active use of MA.
I run HAOS on an Intel i5/9500 with 16GB and was surprised by how quickly MA was increasing the memory demand. Sometimes it was 1 - 2% of total system memory each time I refreshed the screen!
I removed 2.6.3 and reinstalled 2.6.2 but the same trend continued. I re-installed 2.6.3 and it continued.
The chart above shows the continued memory consumption - and the MA restarts from my attempts to identify the problem and stop HASS crashing again. Sadly, nothing has worked and I’ll have to stop MA until I can find a solution.
If anyone has any suggestions, I’d really appreciate them. Thanks
I now understand that there is a known memory leak in the Squeezelite player on 2.6.x. I have been running 2.7.0b15 (beta) for about 24 hours and the memory usage has remained static.
I’ll stay with this version until the release 2.7.x version is available.
I have the same symptoms on my HASS (2026.1.0) with Music Assistant add-on (2.7.3). HASS was very stable until I started MA. HASS run 2 days from the start of MA and next crashed for the first time. From this point server can run only for couple of hours. System monitor shows rapid growing of memory consumption. Without MA everything is OK. I thought that in docker environment it can’t be possible… Yes, I have large music database on NAS server, but another servers have no problem with it (DietPi/MPD on RB3+ 1GB RAM). It is pity because MA looks very well…
