Thanks Martin - This is what I have in the log, not very informative I think. Last few lines would be when I shut the machine down I presume, everything else appears consistent. 2011-10-27 20:53:36 MSG TEST2H[8527]: arguments: /usr/bin/mserver5 --set

I'm using Monet 11.5 on Ubuntu 11.04.
Ive created a database and am attempting to run a series of queries against it with a test script. This is in attempt to use Monet with Apache Jena. I had earlier mailed about a problem with temp tables, but have dodged that by using the monetdb account for now.
The first few succeed, but then I get the following error:
java.sql.SQLException: Read from localhost:50000: End of stream reached (mserver still alive?) Can you check the tail of the merovingian.log file in the dbfarm? It may report on issues encountered during the request. (Please note the time stamp)
Why does this happen, under what circumstances does it arise ? Is there anything I can do to avoid it ?
This is the query that it fails on:
