Hi, I recently upgraded my server from Debian 10 to 11 and encountered a problem where apache2 crashed when a URL to type-map without ".var" suffix was getting accessed.
I created a small example using Docker and put on GitHub so that everyone could easily reproduce this problem. https://github.com/skhrshin/apache2-crash-example * Steps to reproduce * 1. Clone the repo into somewhere 2. Run `docker-compose build` 3. Run `docker-compose up` 4. Access to http://localhost:8081/board.cgi with your web browser 5. In a few seconds, the process is terminated. You'll see errors in the log file like below: [Thu Sep 29 18:32:42.176871 2022] [cgid:error] [pid 209665] (104)Connection reset by peer: AH01248: Error reading request on cgid socket [Thu Sep 29 18:32:42.177025 2022] [cgid:error] [pid 209704] [client ***.***.***.***:53380] End of script output before headers: board.cgi [Thu Sep 29 18:32:43.161802 2022] [cgid:error] [pid 209664] AH01239: cgid daemon process died, restarting [Thu Sep 29 18:32:44.170387 2022] [mpm_prefork:emerg] [pid 209706] (22)Invalid argument: AH00144: couldn't grab the accept mutex [Thu Sep 29 18:32:45.170296 2022] [core:alert] [pid 209664] AH00050: Child 209706 returned a Fatal error... Apache is exiting! Please tell me if there is something I can/should do for reporting it to the bug tracking system. I'm not sure what package is causing the problem.
