Description
Hi
Report a bug in ngx_http_perl_module.
http://nginx.org/en/docs/http/ngx_http_perl_module.html
When reloaded(systemctl reload nginx), it becomes segfault. In this environment. Perl 5.28.2 does not have this problem.
regards,

Just a note: we've seen previous reports about similar problems with Perl 5.30, without any perl-related configuration in nginx, see this thread. From the information available it looks like a bug in Perl.

Thank you for important information.
Perl 5.28.2 has no problem, so use this version.
The following are additional comments on the confirmed phenomenon.
With nginx reload, the following message may be output to nginx error.log
--- error.log
2019/08/14 16:34:15 [alert] 23659#23659: perl_parse() failed: 1
Please provide stack trace and full configuration.
