Sagent Data Flow Service stopped by Windows with error "Data Execution Prevention"

Issue

Sagent Data Flow Service stopped by Windows with error "Data Execution Prevention". No plans can be processed anymore.

Cause

This happens due to DEP feature of Windows.

Explanation for DEP 

Data Execution Prevention (DEP) feature in Windows prevents code execution from data pages. Typically, the code is not executed from the default heap and the stack. Hardware enforced DEP detects code that is running from these locations and raises an exception when the execution occurs. Software-enforced DEP can help prevent malicious code from taking advantage of exception-handling mechanisms in Windows.

Resolution

UPDATED: March 28, 2017


To avoid this Sagent process should be opt-out from DEP in Windows. This can be configured by the system administrator.
