SQL query failing while importing work items from csv file

Hi everyone,

I am consistently running into a problem while importing work items using the built-in importer through Eclipse. I have imported probably 2000+ work items without incident, but a number of work items across many of the csv files I have been using throw the following error:

Could not create work item from <file>.csv (Line 2)
CRJAZ0368I A SQL query failed to execute properly on the server.
stmt = select t1.ITEM_ID, t1.STATE_ID from MODEL.CATEGORY t1 where ((t1.PROJECT_AREA_ITEM_ID = ?) and (t1.INTERNAL_CATEGORY_ID = ?)

I have asked the DB admin to look into the issue, but she claims that the particular command runs without issue when she fills in values. I have only seen this happen for maybe 5 work items in total, while other work items of the same exact type, with the same map file, import without issue.

Does anyone know where I could look to find more info about this, or has anyone experienced this before?

Thanks,
- Josh
