■Cause
The Errors are being answered from the Salesforce API.
After reviewing salesforce.com's published documentation, the Force.com Web Services API Developer's Guide states that the query has timed out.
* If you need more detailed information, please contact salesforce.com.
In the past case, this event occurred when the process that exceeds the execution time limit of API, such as acquiring a large amount of data, is executed.
■Workaround
Please change the processing content. The response is returned in a shorter time by limiting the number of data acquisitions.
If the temporarily decline of the response was occurred, it may be resolved by retrying the process. Please refer to "Reference Information" for the retry setting.
* The Connection retry settings can be used in an environment of version 3.0 SP2 or later, or in an environment where "DSS30SP1_120220_03" is applied to version 3.0 SP2.
