Symptoms

The Internal program error: FineNetServerImpl.cpp, 55 error appears when the AddImageFile or Process method is called with the out-of-process loading method.

Cause

This error is caused by the fact that the MultiProcessingMode parameter of the MultiProcessingParams object is set to MPM_Auto or MPM_Parallel.

Resolution

Please set this parameter to MPM_Sequential if you are using the Outproc loading method. Keep in mind that the default option for this parameter is MPM_Auto, so it is necessary to make this change in the code.
