Hi,
the Memory Use Node throws an error on my OS X machine with 16 GB of memory:
ERROR Memory Use 2:1224 Execute failed: ("ArrayIndexOutOfBoundsException"): -1
Any idea what this might cause since it’s working perfectly on another Windows machine.
Kind regards
Mike
Hi Mike,
Yes, and no. We don’t have access to a Mac to test this on unfortunately, so it was implemented based on a ‘best guess’ from online documentation.
Are you comfortable with the mac command line console?
If you are, could you run the following command in the console and paste back the output, including the column headers?
top -l 1
Better still, if you can find the process id (pid) of KNIME while it is running, then if you could try:
top -l 1 -pid followed by the process id.
[This node gets most of it’s output from the Java Virtual Machine instance, but runs a system command and parses the output in an attempt to get the memory actually used by the JVM process, rather than what the JVM thinks it is using - and this is the bit that is going wrong]
In any case, we should probably change the node to report the other values and show a warning that this method failed, as I think the output can be a bit variable from one mac to the next, possibly even between individual users on the same mac…
Thanks
Steve

Could I ask you to check what version of our plugins you are currently using too? (You can do this either from the Help menu, via ‘About the KNIME analytics platform’, and clicking on ‘installation details’ and looking in the plugins tab, or be browsing to the plugins directory of your knime installation) It is possible that this was fixed on the version on our current nightly build, which I will be moving to the stable builds with the other updates.

Thanks - I think this was fixed in v1.18.3, which is only available on the nightly build at present. However, as I am making other changes right now, I will see if I can make it more robust too, as this is a potential danger area as we rely on the OS configuration, regional code page, and all sorts of other potential pitfalls, for that particular value.
Will let you know when the current version is updated, and will also be migrating that over to the 3.7 stable build at the same time or very shortly afterwards.
Steve
I am happy to aid you in conducting tests on OS X if you like.
Thanks! The node has now been updated on the nightly build, and will shortly be released on the 3.7 stable branch. See
for further details and announcements.
Be good to know if it is now working on Mac OS for you!
Steve
I can confirm it’s working now. Much appreciate your blazing fast and superior support! Thanks a lot Steve.
