After upgrading to 19.11, the Avamar data collection request fails with an error unexpected EOF from worker process. This is observed when running the Avamar jobmonitor request.

The following is observed in the agent logs after placing the Agent in Debug Low logging and rerunning the data collection request:

This is a known issue in Data Protection Advisor.

The vcruntime140.dll module is missing on the DPA Application server.
The DPA Avamar data collection module (dpaagent_modavamar.exe) requires this module.
 
The vcruntime140.dll module is in the Visual C++ 2015 redistributable package (x64) for Microsoft Windows.

There is no permanent resolution to this issue. The issue is still under investigation by Dell Engineering.

There is a workaround available for this issue.

On the DPA data collection server, install the Visual C++ 2015 redistributable package (x64). This package is available for download directly from Microsoft.
After installing the package on the DPA data collection server, restart the DPA Agent.
