While starting on Debian Linux on a very small ARM SBC (SheevaPlug based Seagate Dockstar) with only 128 MB of physical memory, Squeezelite allocates up to 80 MB of reserved memory then OOM Killer kicks in and kills it.

Squeezelite reported version is

Squeezelite v1.9.9-1403, Copyright 2012-2015 Adrian Smith, 2015-2021 Ralph Irving. See -t for license terms

and dmesg shows this:

Please note under Arch Linux running on the same SBC, Squeezelite v1.9.8-1344 allocates less than 9 MB reserved memory.

What did made the memory footprint become so huge? Compile options are the same for both versions.

Hi @famigliabormidavigna . I maintain the Debian packaging of squeezelite and am curious to understand what is happening here. Note from your output above, you are compiling the software yourself and not using the Debian squeezelite package, for which the latest version is v1.9.9-1395.

First a question. Why are you building for Debian but testing a different version on squeezelite for Arch Linux? Is the memory usage equivalent for squeezelite v1.9.9-1403 on Arch Linux?

Assuming that the difference in memory usage is due to the OS distribution and not related to version of squeezelite, the difference could be in the libraries squeezelite is linked against. You can start by looking the version of glibc and whether you are using an alternative malloc implementation, for example, jemalloc on Arch. In order to investigate further, please provide:

  1. the output of ldd -v /usr/bin/squeezelite for builds on both operating systems
  2. the versions of both operating systems you are using
  3. your build options for the Debian version so they can be compared to those used for Arch Linux
  4. the output of pmap -x $squeezelitepid on both operating systems

I am assuming all other variables are the same - that is, you are using squeezelite to stream from the same source on both operating systems and running for the same duration, that the kernel version is the same (or very similar), and that the OOM killer is configured identically for both distributions. But those could also be factors.

Hi tmancill

Hi @famigliabormidavigna . I maintain the Debian packaging of squeezelite and am curious to understand what is happening here. Note from your output above, you are compiling the software yourself and not using the Debian squeezelite package, for which the latest version is v1.9.9-1395.

Great! I had a feeling I was posting in the right place.
Pleae note that in the Debian repo I am using the latest squeezelite version is 1.9+git20210102.78fef68-3 and this is my /etc/apt/sources.list

First a question. Why are you building for Debian but testing a different version on squeezelite for Arch Linux? Is the memory usage equivalent for squeezelite v1.9.9-1403 on Arch Linux?

Long story...
I am using, as some other hobbyst out there I suppose, a single board computer based on the ARM Kirkwood SOC, specifically a Seagate Dockstar, that was itself based on the SheevaPlug. It is an armv5tel architecture. This was supported by Arch Linux ARM https://archlinuxarm.org/ up to late february, then the developers decided to pull the plug since it was residual (and no longer in production since a few years).
I then decided not to dump all the hardware I have been lying around my house and some friends places and switch to the Linux Kernel Kirkwood package and Debian rootfs (bullseye) provided by Doozan https://forum.doozan.com/read.php?2,12096
On Arch Linux ARM the latest squeezelite versione available (to me at least) was v1.9.8-1344 and memory usage was far lower and different. Cannot install later squeezelite versions anymore from Arch Linux ARM since they removed support and their repo isn't available anymore for armv5tel. Cannot even try to compile latest version myself since might not have all the dependencies.

Assuming that the difference in memory usage is due to the OS distribution and not related to version of squeezelite, the difference could be in the libraries squeezelite is linked against. You can start by looking the version of glibc and whether you are using an alternative malloc implementation, for example, jemalloc on Arch. In order to investigate further, please provide:

1. the output of `ldd -v /usr/bin/squeezelite` for builds on both operating systems

2. the versions of both operating systems you are using

3. your build options for the Debian version so they can be compared to those used for Arch Linux

4. the output of `pmap -x $squeezelitepid` on both operating systems
  1. please find the output attached to this post, named clearly I hope
    squeezelite-alarm-ldd.txt
    squeezelite-debian-ldd.txt
    2. uname -a reports Linux squeezedock 4.4.271-1-ARCH #1 PREEMPT Sun Jun 6 01:22:10 UTC 2021 armv5tel GNU/Linux for the host with Arch Linux ARM and Linux debian 5.18.6-kirkwood-tld-1 #1.0 PREEMPT Fri Jun 24 15:26:02 PDT 2022 armv5tel GNU/Linux for the host with Doozan's Debian bullseye: is this enough? I know kernels are a universe apart, but cannot help more than this due to Arch Linux ARM no more supported on this board...
  2. On Debian I just modified this line of debian/rules from export OPTS := -DDSD -DFFMPEG -DRESAMPLE -DVISEXPORT -DLINKALL -DIR -DUSE_SSL to export OPTS := -DDSD -DFFMPEG -DRESAMPLE -DVISEXPORT -DLINKALL to remove SSL and IR thinking those might be the cause of the huge memory footprint.
  3. please find the output attached to this post, please also note that I manage to get the pmap output on Debian in the few seconds between starting squeezelite and when the OOM Killer kicks in, squeezelite never runs for more than a few seconds, 5 maybe, no more than 10 secs.
    squeezelite-alarm-pmap.txt
    squeezelite-debian-pmap.txt

I am assuming all other variables are the same - that is, you are using squeezelite to stream from the same source on both operating systems and running for the same duration, that the kernel version is the same (or very similar), and that the OOM killer is configured identically for both distributions. But those could also be factors.

Yes, the LMS Server is the same, as you can see from the command line included in pmap output. Regarding running duration, on Debian squeezelite gets killed after a few seconds after it has been started, either by systemd or by command line. Kernel version unfortunately are vastly different (Arch Linux ARM runs 4.4.271 while Debian bullseye runs 5.18.6). OOM Killer is configured as by default for both distro, no idea whether configuration is actually the same.

Thanx for your support!
Hope this helps to make squeezelite on Debian better.

Paolo.

P.S. I also installed squeezelite on an i386 box, running Debian bullseye and using stock squeezelite from the default repository: the pattern of virtual and reserved memory reported in htop are quite similar to the ones for Debian on ARM (80 MB reserved memory). Since the box has 1 GB RAM and little else running, everything runs fine, including squeezelite.

Hi, just to mention that I've encountered the same issue (OOM killing squeezelite) on a Raspberry Pi Model B Rev 1 running Raspbian v11.6:

root@XXXXXXXXXXX:~# uname -a

When I run this version I get this in the command line:
