that still happens with 2.4.25

"killall httpd 2> /dev/null" in a script starting a temporary httpd for php-pgo-profiling since it's a SIGTERM should not leave them and finally fail after enough runs to allocate shm segment for auth_digest until you reboot

  killall httpd 2> /dev/null
  sleep 2
  rm -f "$PROFILE_ROOT/php.ini"
  rm -f "$PROFILE_ROOT/httpd.conf"
  rm -f "$PROFILE_ROOT/logs/sess_"*
  rm -f "$PROFILE_ROOT/logs/authdigest"*
  rm -f "$PROFILE_ROOT/logs/httpd.pid"
  rm -f "$PROFILE_ROOT/logs/modsec"*

the 256 bytes are pretty clear from "AuthDigestShmemSize 256"

$HTTPD_BINARY -X -f "$PROFILE_ROOT/httpd.conf" to make sure there is only one httpd process should not take longer than the 2 seconds sleep given that it handles 1500 serial requests within 10 seconds before
