Objet : STDERR not logging after a fix log size

Hi There,

A few days back (on 9th June) I have changed my log_rotation_size to 30 MB and on the same day again reset to 500 MB. for few days it went well, from 15th June itself generating only 30MB files. Now I have reset to 700 MB and reloaded, still am getting the same size of log and the log file is also not rotating.

I have tried changing the log_destination to Syslog which is logging in /var/log/messages however stderr not logging in to the log folder.

FYI ... please check below file stats and the log parameters.
