Out of memory caused by TrimmableHeapBuffer

[juanwippel]

I am facing Out Of Memory issues on Glassfish 4.0 (Build 89) server.

Version of grizzly from \glassfish\glassfish\modules\nucleus-grizzly-all.jar is
version="2.3.1"

Whenever I face this issue, there is always at-least one thread with following dump:
