A recursion bug in the customer's code caused most of a thread's stack to be consumed.
At the end of the recursion, the code stepped into a jvm native call to socketWrite.
While in native code, the stack was exhausted which resulted in a SIGSEGV.

They had not set a value for StackShadowPages and the default value was 3.
This bug is being created to investigate why a value of 3 was not enough to prevent the
stack overflow on the native side.

Here is the end of the stack after the recursion has stopped.
