When I changed to DEBUG log level I realized thath the error is always after UDP Ping.

You need to rerun the database upgrade script from the latest pull merge. There is a new performance table created that is designed to assist large sites. Here is the SQL.

However, I recommend you rerun the database upgrade script as there are other mandatory table changes besides those below.. It can be found in the cli folder.

php -q upgrade_database.php --forcever=1.0.0

CREATE TABLE IF NOT EXISTS poller_data_template_field_mappings (
data_template_id int(10) unsigned NOT NULL DEFAULT '0',
data_name varchar(25) NOT NULL DEFAULT '',
data_source_names varchar(120) NOT NULL DEFAULT '',
last_updated timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (data_template_id,data_name,data_source_names))
ENGINE=InnoDB
COMMENT='Tracks mapping of Data Templates to their Data Source Names';

INSERT IGNORE INTO poller_data_template_field_mappings
SELECT dtr.data_template_id, dif.data_name, GROUP_CONCAT(dtr.data_source_name ORDER BY dtr.data_source_name) AS data_source_names, NOW()
FROM data_template_rrd AS dtr
INNER JOIN data_input_fields AS dif
ON dtr.data_input_field_id = dif.id
WHERE dtr.local_data_id=0
GROUP BY dtr.data_template_id, dif.data_name;
