** Description changed: [Steps to reproduce] 1) launch a focal container $ lxc launch images:ubuntu/focal focal-1897561 2) enter the container $ lxc shell focal-1897561 3) install libnginx-mod-http-perl # apt-get install -y nginx-core libnginx-mod-http-perl 4) check nginx journal # journalctl -fu nginx & 5) reload nginx 2-3 times # systemctl reload nginx Eventually you will see this from the journal: Oct 13 17:13:34 focal-1897561 systemd[1]: Reloaded A high performance web server and a reverse proxy server.

[Workaround] If libnginx-mod-http-perl is not needed, purging it and restarting nginx sidesteps the problem. [Original bug description] Ubuntu 20.04 LTS Looks that Perl 5.30 has bug that causes nginx to die, usually occurs after "service nginx reload" This looks like nginx, but it really is perl issue: https://github.com/Perl/perl5/issues/17154 Fix done in 5.32 (Perl5 commit ffffbf0) and people are asking backport to 5.30 to get fix also to nginx.
