Just today I updated to the latest and greatest (0.15.8.6882). I was several revisions behind and several database updates were done as a result. After the update, I noticed my poller.php processes started taking all the CPU, started getting gaps in the graphs, etc. I noticed thousands of these entries in db.log:
[2015/08/11 22:01:02 -0500] poller.php(21342): Failed dbQuery (#1062 - Duplicate entry '54-2083-6ef88537f91f' for key 'dev_vlan_mac'), Query: INSERT INTO `vlans_fdb` (`device_id`,`vlan_id`,`port_id`,`mac_address`,`fdb_status`) VALUES ('54','2083','220115','6ef88537f91f','learned') [2015/08/11 22:01:02 -0500] poller.php(21342): Failed dbQuery (#1062 - Duplicate entry '54-2084-005056a927c2' for key 'dev_vlan_mac'), Query: INSERT INTO `vlans_fdb` (`device_id`,`vlan_id`,`port_id`,`mac_address`,`fdb_status`) VALUES ('54','2084','220115','005056a927c2','learned') [2015/08/11 22:01:02 -0500] poller.php(21342): Failed dbQuery (#1062 - Duplicate entry '54-2084-a66aaf0bf4cc' for key 'dev_vlan_mac'), Query: INSERT INTO `vlans_fdb` (`device_id`,`vlan_id`,`port_id`,`mac_address`,`fdb_status`) VALUES ('54','2084','220115','a66aaf0bf4cc','learned') [2015/08/11 22:01:02 -0500] poller.php(21342): Failed dbQuery (#1062 - Duplicate entry '54-2085-228a3d193c66' for key 'dev_vlan_mac'), Query: INSERT INTO `vlans_fdb` (`device_id`,`vlan_id`,`port_id`,`mac_address`,`fdb_status`) VALUES ('54','2085','220115','228a3d193c66','learned') [2015/08/11 22:01:02 -0500] poller.php(21342): Failed dbQuery (#1062 - Duplicate entry '54-2086-0ee7c729643b' for key 'dev_vlan_mac'), Query: INSERT INTO `vlans_fdb` (`device_id`,`vlan_id`,`port_id`,`mac_address`,`fdb_status`) VALUES ('54','2086','220115','0ee7c729643b','learned')
If I run a poller process against a switch manually, everything seems to run fine with the exception of the fdb-table module, which is taking over 600 seconds to run.
Here is the schema of my vlans_fdb file:
mysql> show columns from vlans_fdb -> ; +-------------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+-------------+------+-----+---------+-------+ | device_id | int(11) | NO | PRI | NULL | | | vlan_id | int(11) | NO | PRI | NULL | | | port_id | int(11) | YES | MUL | NULL | | | mac_address | varchar(32) | NO | PRI | NULL | | | fdb_status | varchar(32) | NO | | NULL | | +-------------+-------------+------+-----+---------+-------+ 5 rows in set (0.00 sec)

Does my table structure look right? I see someone else on the list has had this same issue, but there is no indication that this should be a problem in the latest version.
What should I check? Thanks for any help.
