Hello All,
We have a Apache/Python/Django using modwsgi. We hit upon a situation where
the following error is happening in the site,
*Error Log*
2019-05-09 09:18:08,471 - root - ERROR] - Error : Traceback (most recent
call last):

IndexError: list index out of range
*My understanding*
I think that the issue is happening because of apache getting reloaded due
to below configurations. At the same time the logrotate triggers 'apache
reload' around the same time.
*Quick Fix*
The quick fix that we had to do was to restart the apache. Just after the
restart the application started working.
*Question:*
What has caused this situation and how to avoid this occurring in future so
that we are not reloading it manually? Thanks,
*Logrotate Configs*
