I have a small SSIS package which contains a single script task. This package is running under proxy account which have access to databases this package is using. The main operation inside script task is we are connecting to Teradata environment and updating some record there. Few months back this package was running fine and suddenly it starts failing intermittently with Teradata connection time out issue so we increased the connection time out. After few days we observed that this package again start failing intermittently with below error.
Code: 0x00000001
Source: Email Sending For IDAccess
Description: Exception has
been thrown by the target of an invocation. End Error
DTExec: The package execution returned DTSER_FAILURE (1).
Started: 11:58:22 AM Finished: 11:59:50 AM
Elapsed: 88.531 seconds. The package execution failed. The step failed.
Any idea or suggestion will be very helpful. For Teradata we are storing the connection string in sql database and using it.
