Syslog service is unable to write to database but, the Test action or Debug SQL command is able to write into the database.
According to this article http://www.kiwisyslog.com/kb/error:-problems-getting-kiwi-syslog-server-to-log-to-a-database/ I have changed the service to an local administrator, there was no change.
I can see some files in creating in DBcache folder for a while and then it stops.
Did anyone tried in this setup, with the above environment ?? Please suggest any debugging with this issue.
