Confirming here we found today dead NGINX hanging on certbot renewals:

7ffcec0a17d0 error 4 in libperl.so.5.30.0[7fa35cb0b000+166000]
Killing off complete and restart helps on the port hogging as @wpcd said.
This feels to drastic so if there's a patch ready let's backport please.

@teward Can we confirm already this one brings remedy or caveats known?

Title:
libperl.so.5.30.0 causes nginx to segfault
Status in perl package in Ubuntu:
Incomplete
Bug description:
[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.

Oct 13 17:13:35 focal-1897561 systemd[1]: nginx.service: Failed with result
'core-dump'.
[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 bf0) and people are asking backport
to 5.30 to get fix also to nginx.
Error:
