Memory Leak in JanusGraph Framework

I am using janusgraph for 6 months. Now getting OOM and after restarting the service It runs fine for 4-5 days. I created the heap dump and generated the analysis chart. I am not able to figure out what is the cause of OOM. Please find the screen shot and help.

Start by reviewing the issue's heap-dump analysis charts and the reported behavior: out-of-memory errors after 4–5 days that temporarily clear after a restart. Identify a reproducible leak and its cause from the available evidence; the issue does not name a source file, test, entry point, or concrete completion criterion.
