It's pretty obvious you have a memory leak. Ever higher heap utilization after GCs, long GC pauses once the heap fills until an OOM causes a restart. I suggest you read this.

I would try -XX:+HeapDumpOnOutOfMemoryError to see if your JVM supports that.

You should place it on the JVM command line, in jvm.options, for example.

OK, so when your JVM runs out of memory it should generate a heap dump and you will need to analyze it. I suggest you keep the heap small so that the heap dump is manageable. If you JVM runs out of heap at 8 GB it will be a lot easier to work with than if it runs out at 48 GB.
