Hi!The kernel fix for CVE-2017-1000364 (mm: enlarge stack guard gap) breaks java application (or at least some), see https://stackoverflow.com/questions/44719488/segmentation-fault-when-starting-jvm-using-jpype
You can change the stack guard gap via kernel parameter: stack_guard_gap= [MM]override the default stack gap protection. The value is in page units and it defines how many pages prior to (for stacks growing down) resp. after (for stacks growing up) the main stack are reserved for no other mapping. Default value is 256 pages.
What is the value to get the previous behaviour?
Many greetings,
Stephan
