I run a batch job that reads a csv file and stores the objects in a database. If I set a large chunk size (greater than 10000), the objects get stored in the database correctly by the writer, but the job itself does not complete (does not go to the next batchlet) and throws the following exceptions. If I lower the chunksize (smaller than 5000), I don't get an error.

I think this might have something to do with it, because I think it shuts down the transaction for the job:

Several minutes later, the objects get inserted into the database and I get this after the writer ends:

Can someone tell me what the problem is? I suppose there is a timeout for the job. Where could I set this? I might still use a lower chunksize, but I want to know the reason for this and how it could be fixed.

Thanks in advance.
