Thread:Project:Support desk/DB Size continously increasing since upgrade from 1.17 to 1.19

Environment: MediaWiki 	1.19.0; PHP 	5.3.10; MySQL 	5.1.61-0+squeeze1.

Since the Upgrade from 1.17 to 1.19 the size of the DB is (slowly) increasing, although there are nearly no new Posts or changes on the Site. (http://vtadwiki.vtad.de/index.php/VTADwiki:Portal)

Size of the 1.17 DB : 60 MB ; size of the 1.19 DB : 79 MB

Is there any log that must be regularly cleaned with an maintenance script?
