System type: 64 - bit
32 gb memory:
On the system deployed solr, then write five threads to solr query, task manager, the physical memory has been growing, finally to 99%,
But the memory process added up to no more than 12 g,
1 with the JDK's own jvisualvm analysis, see if there are memory
Look from the figure, heap will release, so there is no memory leak problem
2 use the RAMMAP analysis, found a lot of memory been Mapped File takes up
Click on the Empty, Empty Working Sets, can release the memory, the task manager memory footprint decreased to 28%
If know how to solve, hope everybody to give directions
