After running daily maintenance script, the log of 'proxy_access_log' and 'proxy_access_ssl_log' are become 0KB size.
It is expected behavior. Data from '
proxy_access_log' and '
proxy_access_ssl_log' is merged with '
access_log' for further statistics calculations, whilst the logs themselves start over, so that web server continue write logs while statistics for the past day is being calculated.
