Nexus IQ Jenkins Platform Plugin - tmp cleanup

Hello everyone,
we’re using Nexus Platform Plugin 3.8.20200310-130318.c482b58 on Jenkins 2.222.1.

We’re experiencing an issue, that scan results appear in the /tmp directory (files scan*.xml.gz) but won’t be cleaned up, thus filling our file system.

What can we de to avoid this? Is there any option to think about? I could not find anything regarding this in documentation.

Regards
Axel

I’ve just seen, that there is a ticket regarding this: https://issues.sonatype.org/browse/INT-1446 and votet for this.
Any further information available?
