I have a bunch of test queries which I am testing against MonetDB. Queries all by itself run fine but if you run the same set of queries in a loop disk runs out of space. I am not sure why would memory map files won't clean up automatically and why do we have to start the server again to clean up these files? Is there a workaround to this problem or is this a known issue in MonetDB?
There was a memory leak issue in the Oct2014 release. A new version of the code 'July2015' has resolved those issues and works fine.
