Subject [users@httpd] apache dead pids
Date Thu, 14 Nov 2019 18:44:12 GMT
We are running apache in our environment with the version 2.4.27

apachectl -v
Server version: Apache/2.4.27 (Red Hat)
Server built:   Jun  6 2018 13:30:38

over period of time I see httpd pids lying around  holding memory and not
serving any more requests as I see no LISTEN attached to that pid.
ps -ef | grep httpd | wc -l
lsof -i | grep LISTEN | grep httpd
In this scenario I see 42 dead pids on one of our node,

<IfModule mpm_worker_module>
  ServerLimit     100
  StartServers     5
  ThreadsPerChild 32
  MinSpareThreads 160
  MaxSpareThreads 320
  MaxRequestWorkers 3200
  MaxConnectionsPerChild   50000

I am not able to reproduce this issue and it happens only on production.

Really appreciate your inputs on this issue.
