Debian trixie - Apache2 - mod_fcgid 2.3.9 - MapServer

[Neubauer, Steffen (VermKV)]

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?
