Help: Database Table Taking 9GB Of Disk Space But Only Contains 50Mb Data.

Disk space is increasing at an alarming rate (about 500MB a day). Shrink of database seems to have no effect. It is a queueing table so data is inserted then a few minutes later it gets processed & deleted.

Here is info about the problem:

sp_spaceused ImporterModuleQueue

name rows reserved data index_size unused

ImporterModuleQueue 30 9469432 KB 9468280 KB 32 KB 1120 KB

This is about 9 GB


select sum(len(QueueContent)) from ImporterModuleQueue

49744918

select sum(len(QueueErrors)) from ImporterModuleQueue

43529

This is about 50 Mb
