Hi all,
this may be a stupid question, but I cannot seem to find the answer.
So, in JavaThread we establish stack guards (red and yellow zones). But I do not find anything similar for non JavaThread threads, e.g. VmThread?
Do we rely on whatever guard mechanism is established by the OS?
The reason I ask is that we deliberately disable OS guard pages on AIX because we found them to interfere with our own guard pages. I wonder whether we now have any overflow protection on the VmThread.
Thanks & Regards, Thomas
