https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D239894 --- Comment #15 from Greg Lewis <glewis@FreeBSD.org> --- Hi Konstantin, It looks like you have been working on the procctl approach based on https://reviews.freebsd.org/D21352. Thanks for doing that! A couple of questions/comments though. Can we help test this approach? I.e., verify that fixes the problem for the JDK? I'm happy to compile a kernel with the changes and see if that resolv= es the issue if that would help. A concern though is that this doesn't address the other problems outside of= the JDK that have been raised in this thread. Those are the issues raced by Ku= rt and Shawn in the comments here including problems with some values of this sysctl making the system unstable or unusable, whether it should be placing pages within the stack at all, and whether stable values (i.e., 0 or 1) actually prevent the stack clash issues at all. Do you see what you're doi= ng as a stop gap prior to longer term work here? --=20 You are receiving this mail because: You are the assignee for the bug.=
