[SOLVED] RAPID MINER hanging

daradara Member Posts: 29 Contributor II
edited November 2018 in Help
Hello I am using Rapid Miner to connect to a  remote Rapid Analytics.

I am using tiny databases of few items and after 5-10 submits to the server the Rapid Miner client freezes.

On IMAC I run it with option to grab up to 8GIG and when it hangs there is about 4GIG of memory left + very little CPU consumption.

Is there a debug option I can turn on to see where and why Rapid-Miner hangs?

Thank you

Dara

    Hi,

    the log file for RapidMiner won't be available before the next release I'm afraid, so you will have to start RapidMiner from the RapidMiner/scripts folder via one of the start scripts, e.g. RapidMinerGUI.bat (Windows) or RapidMinerGUI (Linux/Mac). There you can see possible errors and post them here for further help.

    Regards,
    Marco

    Constantly hangs on my 8GIG new IMAC.

    Here is how I load the RapidMIner:

    java -Xmx8000m -jar rapidminer.jar

    There should be plenty of memory, I basically hang within 3 or 4 execution of almost any process.

    It is not recommended to start RapidMiner this way. You have plenty of memory but you haven't increased the size for PermGen memory.
    Without going into further detail, this is done by the start-up scripts in the scripts folder of RapidMiner.

    Try to start RapidMiner this way:
    ./scripts/RapidMinerGUI.sh

    There you also can increase the size of the memory that should be available.

    Best,
    Nils

    Thanx, somehow this is not easily found in your documentation.

    This might have solved the hanging problem as expected.

    If I do not scream in a day, means all is good

    Thanx
