Generation of .mdmp files
Hi
I figured that on virtual machine my rapidminer server had been hosted there were some .mdmp files(each around 12GB) getting created in the folder where server has been installed.I per my knowledge these files get created if any process crashes.So can you help me to figure out how it is related in context of RapidMiner because these consume a lot of space on disk probably making the server slow as well.

the JVM is responsible for creating these dump files. You can deactivate it by setting this java option:
-XX:-CreateMinidumpOnCrash
If you don't want to pass this parameter via the start command, you can also add it to the default options by adding it to the $server/bin/standalone.conf(.bat) file.Cheers,

We are using server 9.2 and jre 1.8
are you sure that these files were created because of process failures and not by a crash of the JVM?
So far, we've not observed the dump creation for process errors. I would appreciate it if you could provide a minimal example for the mdmp creation issue.
Thanks,
Marcel
