Re: MonetDB causing disk space to fill up

Hello Anu, First of all. Thanks for trying MonetDB. Normally, MonetDB tries to clean up things (e.g., remove/discard temporary files, process the Write-Ahead-Log files) at a regular time and/or if there is some idle time. In your case, it could be that the disk is filled before MonetDB got a sufficient chance to do the cleaning. The WAL files can be large and takes some time to process. Would you please provide us some more information, so that we can look further into your issue: - which monetdb version? We have discovered several leaks in Oct2014, which are fixed in Jul2015 - which OS? - disk size? available disk space? data size? - what do your queries do? read-only queries? or read-only queries intertwined with updates? how exactly? - updates frequency? - In your loop, I assume the same query set is repeated. how many queries are there? Regards, Jennie

Hi,

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?
