FTP Socket <socket number> timeout. The FTP server has not responded in time. Verify the FTP server is running, or increase the FTP timeout value.
The Integration Service tried to accessed a file source on an FTP server, but the FTP server did not send any data before the Integration Service timed out. By default, the Integration Service waits 600 seconds before timing out.
Verify the FTP server is still running. If you need to increase the amount of time the Integration Service waits before timing out, contact Informatica Global Customer Support.
