Some script is probably hogging the workers and not letting them close so if you must, just restart, but judging by the amount of traffic you seem to have at the time I would truncate in logrotate and not restart or reload the server at all.
I run a Python script on the production machine to delete the entire site (including directory structure) then redeploy everything from the repo whenever anything changes.
On the basis that Apache (mod-wsgi) only reads the files once on reload, if they also had the dead finger of my script or perhaps the Python interpreter hanging on, that may well have "hogged" the workers.
That script now restarts Apache instead of reload.I have now adjusted the logrotate script to avoid reload/restart logging status as follows:
/var/log/apache2/*.log {
daily
missingok
rotate 14
compress
delaycompress
notifempty
copytruncate
sharedscripts
prerotate
if [ -d /etc/logrotate.d/httpd-prerotate ]; then
run-parts /etc/logrotate.d/httpd-prerotate
fi
endscript
postrotate
if pgrep -f ^/usr/sbin/apache2 > /dev/null; then
invoke-rc.d apache2 status 2>&1 | logger -t apache2.logrotate
fi
endscript
}
... and left the mpm-event settings as follows:
<IfModule mpm_event_module>
