Librocksdbjni files in /tmp directory

We’ve been running the HiveMQ CE for a while now, and we just found out that in the /tmp directory it has created a bunch of files called “librocksdbjni{nr}.so”. All 8.1MB.

What are these files, why are they here, and can they be safely deleted?

Hello Netvibes,

these are the files where HiveMQ CE stores its persistent data. See [](Rocks DB).
These files are not safe to remove.

Regards, Yannick

I thought all the persistance data was saved in the /opt/hivemq/data/persistence directory?
