Timeout in SSIS package running DBCC CHECKDB

I have created an SSIS package to run DBCC CHECKDB on all the databases on the server and send error messages by email. But for several of the databases, I get an exception running my script: > Timeout expired. > The timeout period elapsed prior to completion of the operation or the server is not responding. The only timeout I can find in the project/package is set to 0, which I presume means no timeout. DBCC CHECKDB runs from SSMS just fine.
