This is the second thread about this issue that loops in the Apache 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?
Do you have the results with nginx? https://alioth-lists.debian.net/pipermail/pkg-grass-devel/2025-December/117047.html Kind Regards, Bas -- PGP Key ID: 4096R/6750F10AE88D4AF1 Fingerprint: 8182 DE41 7056 408D 6146 50D1 6750 F10A E88D 4AF1
