There are quite a few if you search. We saw this for weeks, except ours was 
dumping core when it happened. Unless you’re already running RHEL10 you’ve got 
an older Apache httpd which doesn’t have a fix for the problem of threads left 
open by inactive sessions during the reload.

It’s a restart failure which aligns 100% with this reported bug 
https://bz.apache.org/bugzilla/show_bug.cgi?id=53555

There’s documentation about this on 
https://httpd.apache.org/docs/2.4/mod/event.html#graceful-close

Here’s the configuration change we applied which has completely remediated the 
problem for us.
# Minimize open/idle sessions
MaxKeepAliveRequests 20
# Multiply by ThreadsPerChild for total concurrent sessions
MaxRequestWorkers 400
# 16 to handle Req*Thread, 48 to handle gracefully restarting process
ServerLimit 64
