In the nightly build for aarch64 RPi4 connmand leaks socket file descriptors, just do

# lsof | grep connmand 
551     /usr/sbin/connmand      0       /dev/null
551     /usr/sbin/connmand      1       /dev/null
551     /usr/sbin/connmand      2       /dev/null
551     /usr/sbin/connmand      3       anon_inode:[eventfd]
551     /usr/sbin/connmand      4       anon_inode:[signalfd]
551     /usr/sbin/connmand      5       socket:[483]
551     /usr/sbin/connmand      6       socket:[486]
551     /usr/sbin/connmand      7       /dev/urandom
551     /usr/sbin/connmand      8       anon_inode:inotify
551     /usr/sbin/connmand      9       anon_inode:inotify
551     /usr/sbin/connmand      10      socket:[504]
551     /usr/sbin/connmand      11      /dev/rfkill
551     /usr/sbin/connmand      12      socket:[6422]
551     /usr/sbin/connmand      13      socket:[674]
551     /usr/sbin/connmand      14      socket:[6438]
....

and note the high numbers in the third column (file descriptors), wait 2 minutes and rerun to see it's increasing (until it tops out at 1024 which is the process's open file limit). I discovered that investigating after lots of messages "connmand: Failed to bind time server socket" after a few hours of uptime.

A debug log can be found at https://paste.libreelec.tv/enabled-lynx.log

I reverted just the subtree packages/network/connman to 19fa1111 "connman: dbus: Use non-deprecated installation path" and there's no leak, the number of file descriptors remains stable around 25.

Here's another crash log, produced with a build with DEBUG=Python3,kodi

http://ix.io/3PLX

This time no Youtube involved, I just played a few minutes of a local movie, stopped it and "Reset resume position".

All my crashes, whatever the apparent activity was, show a segfault in thread 1 with identical (at least) 10 top frames, all executing python code.

I have the same problem: Kodi crashes regularly, looks like when it tries to update some sqlite3 database. In the following crashlog Kodi crashed after I stopped viewing a Youtube video (with plugin.video.youtube). Tested with LibreELEC-RPi4.arm-11.0-nightly-20220215-f42fa56.tar

Note that the SEGFAULT occurs in /usr/lib/libpython3.9.so.1.0 and this behaviour started with the switch from python 3.8.x to 3.9.x (#6227)

I have a build with DEBUG=Python3,kodi and can reproduce the crash with that.

Quote from HiassofT

Thanks for the log, I could reproduce the VIDIOC_DQEVENT errors and PR'ed a fix for it https://github.com/LibreELEC/LibreELEC.tv/pull/5888

Thanks, the problem is gone in LibreELEC master with your PR applied (62b201b).

I see similar behaviour (LibreELEC-RPi4.arm-11.0-nightly-20211117-df8716a.tar):

video freezes for a few seconds while audio continues, then suddenly video catches up. When the video has finished playing the last frame is still displayed until I explicitly stop it.
