Duplicate Entries in cubecart_seo_urls

[TDLWebs]

Hi,

When viewing the System Error Log I am noticing lots of errors like the following:

File: [seo.class.php] Line: [723] "INSERT INTO `CubeCart_seo_urls` (`redirect`,`type`,`item_id`,`path`,`custom`) VALUES ('0','prod','3795','london-transport-bus-timetables/london-transport-road-and-rail-timetable-1947-gravesend-and-district.html','0');" - Duplicate entry 'london-transport-bus-timetables/london-transport-road-and-rai...' for key 'PRIMARY'

Any idea why this is happening?

I have upgraded to version 6.4.2 cleared the cache etc.

I had a similar issue when I moved to a new server, had to take the site offline and purge all caches, did the trick.
