Large MDMP Files Generated

[benevarts]

KNIME is generating Enormous (200+ GB) MDMP Files) and it’s clogging up our drives. Any ideas on how to resolve this issue. We’ve deleted the files, but I assume they’ll continue being generated in the future

I have the same issue and I was not able to solve the problem. It’s really serious because it’s clogging up the Hard drive.

Any ideas?

Maybe this helps?

MDMP data dump file

Hi @venturaz87, @iiiaaa, These mdmp files you’re seeing are so-called Minidump files. The Java Virtual Machine (JVM) produces these files such that you may diagnose what led to the crash. To prevent your JVM from creating these Minidump files on crash, can you try putting the line -XX:-CreateMinidumpOnCrash into your knime.ini? Best, Marc

Just tried this, hopefully it will work (just have to wait for a crash to test it…) thanks!

Hi @benevarts -

Still investigating this MDMP dump issue. In the meantime, can you provide any additional detail on why KNIME is crashing in your case? Thanks!

Hi @ScottF,

It was a while ago now (and we haven’t had issues since) but I believe it was out of memory crashes (probably also why the files were so large…)
