https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197789 --- Comment #4 from Michelle Sullivan <michelle@sorbs.net> --- Ok got it down to something a little more clearer... No changing of vm.kmem_size_max has any effect except delaying the issue... just as vm.kmem_size doesn't. What does stop the panic (so far I've build 800+ packages using poudriere - with 'svn update' prior - which before the update didn't even complete and after going through several boots it manages around 20 packages before panicing - if it even gets past the checking sanity phase).... Reduce the CPU count to one cpu .... Interestingly setting max ARC size to 40M and within minutes of multiple CPUs it's over 400M ... before it panics... With one CPU it grows to 80(ish)M and doesn't panic... some 40 or 50 cores publicly available at the link i post earlier... both 9.2 and 9.3 are affected... lets hope someone will see to patch it before 9.4.. I wouldn't have a clue where to look for the issue or I'd take a shot at it myself. -- You are receiving this mail because: You are the assignee for the bug.
