Very large files in the Ignition's directory

Does somebody know what are theses files that use a lot of space in the Ignition’s directory?

Thanks.

Pretty sure that’s a “MiniDump” file from a crash. Ironically named. /-:

Memory dump… you or someone else must have added -XX:+HeapDumpOnOutOfMemoryError to your ignition.conf???

No. I just check and that switch is not set in the ignition.conf file.
