OOM without a full GC with G1GC

[nezih yigitbasi]

Hi,
In one of our systems I have recently seen a JVM (1.8.0_112-b15) has gone
OOM without triggering a full GC. The interesting thing is, even if the
heap is close to almost being full a full GC is NOT triggered, and then an
OutOfMemoryError is thrown. Adding to that when I look at the heap dump the
total retained size of all the objects is ~60G, which suggests that there
was plenty of reclaimable space.

Any ideas about what may be going on here?

Here is the GC logs:

Here is a list of our JVM args:

Thanks,
