Zooming in on this aspect: this would suggest that your heap memory is 
being kept "pinned" somewhere.

Are you, by any chance, using downcall method handles with the 
"critical" Linker option? Or any form of critical JNI?

It wouldn be interesting (separately from the "architectural" angle 
discussed in my previous reply) to see which method call(s) is causing 
this exactly...
