Error when deleting a full text index

Hi,

I get the following error when trying to delete a full text index of a large table (more than 13 million rows/documents).

Could not execute 'DROP FULLTEXT INDEX TEXT_MINING.MEDLINE_INDEX' in 4:22.793 minutes .

SAP DBTech JDBC: [2048]: column store error: index delete error:  [6010801] message not found;object=TEXT_MINING:$TA_MEDLINE_INDEXen

Thanks for the help,

Mariana
