Attached is the patch upstream backported to the 2.4.x branch. It applies cleanly to bionic and focal's apache2 (with -p4), but jammy already has this fix.
>From what I understand, this is an issue that crops up only when apache2 is under intense load, so identifying a reliable test case may be a challenge. However, the fix makes sense and the patch seems reasonable to me. ** Patch added: "mpm-event-fix-overspawned-children-ignored-on-graceful-restart.patch" https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1979942/+attachment/5605446/+files/mpm-event-fix-overspawned-children-ignored-on-graceful-restart.patch ** No longer affects: apache2 (Ubuntu Impish) ** Also affects: apache2 (Ubuntu Bionic) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server/Client Support Team, which is subscribed to apache2 in Ubuntu.
