Forum OpenACS Development: aolserver stops responding sometime after running query on sql database

Continuing on with my description of the last error, just over an hour after I ran the query to my sql database, aolserver stopped responding after throwing these notices:
[-sched-] Notice: dbinit: closing old handle in pool 'yardi'
[-sched-] Notice: nsfreetds: DbClose(yardi) called.
[-sched-] Notice: nsfreetds: DbCancel(yardi) called.
Do I need to release the handle to my sql database after I run the query? Thanks.
