Rapidminer hangs at startup

RacalRacal Member Posts: 5 Contributor I
Hi,

I experience following problem:
At startup (./RapidMiner-Studio.sh), Rapidminer hangs at "Initializing checks"
When I delete the ~/.RapidMiner directory, startup succeeds, but only then, if I start up again, it hangs again.

- Rapidminer 9.8
- Linux mint 20
- Java java-8-openjdk-amd64
- Working memory = 10Gb


I do notice Java is eating up my memory.
I set the setting of maximum  memory usage for Rapidminer at 1Gb, 2Gb, 3Gb, ..... to no avail...

anyone with a suggestion as to solve this?

many thanks.

    Dear Jonas (and Marco),

    great! This seems to have solved it. Started 2 consecutive times with no problems!
    Many thanks!

    ps: I forgot to state that I use the XFCE version of Mint, but still gnome has influence clearly
    pps: there have sneaked some html codings into your script :
    2>/dev/null &&amp
    again, many thanks!
    Kind regards, Marc

    Hi,

    Could you please post the content of the rapidminer-studio.log from the USER_HOME/.RapidMiner folder here?

    Also note that we recommend at least 16GB of RAM (or much more depending on what kind of data and operations you plan to do), though for small tasks it should work with as little as 4GB.

    Regards,
    Marco

    Hi,

    Thank you for providing the log!
    Unfortunately, it contains nothing unusual :(

    If you are up for it, I'd love to see some very specific debug information, which you can acquire the following way:

    1. Start Studio, wait until it hangs.
    2. Run the following in the shell: jcmd (It should be located in the JAVA/bin folder). That gives you the process id of RapidMiner Studio.
    3. The id you got back insert into the following command by replacing {PID} with it: jcmd {PID} Thread.print
    This gives you a list of stacktraces for each thread of Studio, and thus hopefully more insight into what exactly hangs.
    Though my gut feeling is that something does not play nice with the latest Linux distribution versions, seeing as Ubuntu 20 also seems to share the problem..


    Thank you,
    Marco
