i've experienced a strange Error while trying to import data for Entity "Company". I''ve a 800 MB File full of Company Data and splittet it in 60-70 MB Files (.xlsx) just for testing.

Now everytime i start the import directly on the Server i got an "404 File or Directory not found" Error.

Everytime i start an upload/import on the Client with the same file i got a "Connection lost" Error.

With Files <= 5000KB everything's ok! I've searched for max. File size for importing/uploading but haven't found anything. And we've definitely have enough memory in every way on the server.

Any suggestions are appreciated!
