Hi Maintainers, I have a problem with Debian 13 in the interaction of Apache2, FCGI and MapServer. The Apache2-FCGI-MapServer combination has always worked very well from Debian 7 to Debian 12!
Migrating from Debian 12 to Debian 13 has caused problems with the Apache2 module mod_fcgi. In conjunction with MapServer processes, the RAM usage per FCGI process increases over time until the memory is written to swap, causing the VM to experience issues. I was only able to resolve this by closing the FCGI processes after 5-10 minutes instead of the usual 60 minutes. A VM has approximately 70-110 FCGI processes running. Previously, a process could manage with approximately 300 MB, but now I have seen processes that ran with more than 2 GB before I had to restart Apache. Is this behavior known for Apache2 (2.4.65-2)? Or is there a new parameter I'm unaware of? https://packages.debian.org/de/trixie/apache2 https://packages.debian.org/de/trixie/libapache2-mod-fcgid https://packages.debian.org/de/trixie/cgi-mapserver Mit freundlichen Grüßen Im Auftrag Steffen Neubauer
