When import large Projects via qcp File Server Error EoF

Hi All, 

when I import a project via Project File from and older ALM Installation (Version 17.0.1) to a new Version (24.1) installation, I get the error Message 

In the log Files: 

Failed to import project. Project will be deleted

com.hp.alm.platform.exception.CTdException

Messages:
Error on copy from input stream to output stream;
Early EOF;

....

__________

Creation of project failed : org.eclipse.jetty.io.EofException: Early EOF

com.hp.alm.platform.exception.CTdException

Messages:
Failed to import new project '%PROJECTNAME%';
Error on copy from input stream to output stream;
Early EOF;

Stack Trace

Because the qcp File is 1,1 GB I thought of performance. 

I Updated the Server Performance, now the Server has lots of more performance than the old Server. 

The Network is stable too. Any Idea what I can do next? 

Best wishes, 

Stefan
