A new thread has been opened with a proposal to integrate a solution to this problem in the (Open)Suse / MicroOS ecosystem.
OpenSUSE Proposal: RAM memory limiter management for Badoo file indexing service
This thread includes a script with a temporary workaround u can use prior to large file operations that require baloo fis processing large amounts of metadata. This is to prevent it from triggering a memory leak causing the ram memory to overflow to an extend the system is completely hanging or halting.
