Since updating the LTS server version from 20.04 to 22.04, I've had problems with apache 2.4.52 (2.4.52-1ubuntu4.1) in mpm_event mode. The child processes for apache fail to start after a period of time. The webserver is unreachable. In netstat there are many CLOSE_WAIT and ESTABLISHED entries.

The error_log says:

[Tue Aug 30 12:59:38.451188 2022] [http2:warn] [pid 687247:tid 139925644072832] AH10291: h2_workers: cleanup, 1 idle workers did not exit after 5 seconds.

Other processes are gone.

The problem is known and already fixed in 2.4.53, see: https://bz.apache.org/bugzilla/show_bug.cgi?id=65769

I haven't found anything that this problem has already been fixed in the ubuntu version of apache. That's why I'm making this bug report.

Many Thanks.
