On Guix, for a freshly launched Jami at version 20230206.0 but with the latest Jami pjproject commit, I have 923 open files: jami-lsof.txt

jami -d logs: jami-20230206.0-siploglevel-5.log.gz

Logs collected until crash Trace/breakpoint trap. jami-20230206.0-siploglevel-5.log.gz

OK, better logs, with accompanying lsof -p$(pgrep jami) output.

gdb.txt jami-20230206.0.log.gz jami-20230221.0-open-files-after-15m.txt jami-20230221.0-open-files-after-crash.txt

Seems some thread is not finished. I see two things:

1. 700+ eventpoll
2. 170 sockets to 192.168.10.1:5351

Fresh logs, with gdb.txt having some symbols. gdb.txt jami.log.gz jami-lsof.txt

New try, with --no-grafts in an attempt to help with debug symbols (also added qtbase:debug and glibc:debug to the mix): gdb.txt jami.log.gz jami-lsof.txt
