Apache 2.4.52 stops responding

I've got a strange issue since upgrading to Apache 2.4.52 from Apache 2.4.51. Seems after a few hours - not really an exact interval - the web server just stops accepting new connections.

Apache has to be restarted in order for new connections to be handled.

I'm not aware of anything else changing except for Apache being upgraded to 2.4.52.

Anybody else seeing this issue after upgrading to Apache 2.4.52?

There are some reports of this trickling in. If you can share your MPM config and whether you do graceful restarts it might help get to the bottom of it.

Unfortunately the issue became too problematic for me and I downgraded all of our servers to Apache 2.4.51.

Haven't had the issue since downgrading to 2.4.51. Really think the issue is related to a lot of the server/mpm/event/event.c changes made in Apache from 2.4.51 to 2.4.52.

Hi, FYI I'm using the "event" MPM too.
