Does Nifi use memory other than allocated Heap Memory?

Explorer

We have given 4GB of memory to heap by mentioning it in bootstrap.conf and all repositories (Content, Provenance, Content & FlowFileRepository) are configured to Disk. DistributedCacheServer is also configured to use disk. But when NiFi instance runs for a while It starts using 10 GB of memory.


Not able to find where the extra 6 GB of RAM is consumed. Please help.

@Kapil Kaushik

One way additional memory that could be associated with nifi user would be if in the flow there was a processor that was starting an external process. That process would be owned by the nifi user and would appear to be associated to the NiFi process.

What types of processors are in the flow?
