Cannot fetch data from repository

Hey, 

I am using RM Server and I ran several processes on the server and it worked. But in all of a sudden I get an error message like this when I want to open the result table in RM:

 

Connot fetch data from repository.

Cannot parsse I/Object:java.lang.ArrayIndexOutOfBoundsException

 

I am new on working with RM Server so I have no clou. On the web interface I can see the meta information and I can display the data in html... but not in the RM client. And if I download it as an excel file there is no data in the excel file. 

The bad thing is that the process lasts more than one hour so it it really really frustrating...

 

Thanks in advance

Marcel

    Hallo Marcel,

     

    any chance to have a look at the server logs? See: http://docs.rapidminer.com/server/administration/error-logs.html
