SYSLOG Message are not getting removed

[sharekhan]

Earlier i was getting the below error,
06/22/2016 10:45:01 AM - CMDPHP: Poller[0] ERROR: A DB Exec Failed!, Error:'1305', SQL:"DELETE FROM `syslog`.`syslog_incoming` WHERE message (facility='user' AND priority='warning' AND message='pam_unix(cron:session): session opened for user www-data by (uid=0)') AND status='6''

So i have followed yours the SQL match expressions for Syslog Removal Rule Filters, through that the above error gone but still the messages are not getting deleted from the syslog console.


Code:
facility='Syslog' AND priority='Info' AND message='restart'

But for some unclear now to me reasons my functions.php at line 344 looks like that
Code:
$sql = "DELETE
FROM `" . $syslogdb_default . "`.`" . $table . "`
WHERE " . $remove['message'];

pls help...
