Re: [syslog-ng] db-parser reuse for multiple logs?

      Hmm. I dont see what dbparser is trying to persist there. Now as I think of
it, its probably the correlation state table.

This seems to be a genuine bug.

Hi
Are db-parsers defined in syslog-ng configurations not reusable for
multiple logs?  A simplified example (syslog 3.6.2):
parser myparser {
        db_parser(
                file("/usr/local/etc/patterndb.d/myparser.xml")
        );
};
template mytemplate {
         template("${A};${B};${C}\n");
}
filter filter_host1 {
        netmask(10.0.0.1/255.255.255.255);
};
filter filter_host2 {
        netmask(10.0.0.2/255.255.255.255);
};
destination dst_host1 {
        file("host1.log" perm(0644) template(mytemplate));
};
destination dst_host2 {
        file("host2.log" perm(0644) template(mytemplate));
};
log {
        source(src_udp);
        filter(filter_host1);
        parser(myparser);
        destination(dst_host1);
        flags(final);
};
log {
        source(src_udp);
        filter(filter_host2);
        parser(myparser);
        destination(dst_host2);
        flags(final);
};
This seems to work as expected and 'syslog-ng -s' does not report any
problems, but I see the following in the syslog-ng internal log:
Internal error, duplicate configuration elements refer to the same
persistent config; name='db-parser(/usr/local/etc/patterndb.d/myparser.xml)'
Internal error, duplicate configuration elements refer to the same
persistent config; name='db-parser(/usr/local/etc/patterndb.d/myparser.xml)'
