Hi,
I have an apache-2.4.46 system with php-7.4.16 on fedora33 site using cloudflare, although I'm not sure if it's related. This is an entry from our logs from a cloudflare IP:
172.68.34.214 - - [11/Apr/2021:21:22:11 -0400]
"GET
/advisories/gentoo/gentoo-glsa-200903-10-irrlicht-user-assisted-execution-of-arbitrary-code

ls443 s:500 V:linuxsecurity.com v:linuxsecurity.com
The full URL for that entry is:
https://linuxsecurity.com/advisories/fedora/fedora-32-subversion-2021-16e51e39a6-20-34-36?rss
This page does not produce a 500 error when I go to it manually.
The LogFormat for this entry is as such:
LogFormat "%h %l %u %t \"%r\" %>s %b
\"%{Referer}i\" \"%{User-agent}i\" %T/%D %I/%O/%B H:%H U:%U
ls443 s:%>s V:%V v:%v" timing
The %b in the entry above appears to be 121 megabytes. How is that possible? How can I debug this? I have display_errors = On in my PHP settings and have debugging enabled for php-fpm but no errors are being reported.
Thanks,
Dave
