https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=212150 --- Comment #3 from openjdk@getsnappy.com --- I'm glad it helped. I agree that this is just a workaround and not a fix. I took a peak at libthr and I don't believe there is a way to detect a native stack overflow. I also looked into the default sizing logic and it looks like the default is identical to Linux, at 1M for 64bit architectures. It looks like the default non-initial thread stack size is 2MB for 64bit architectures, so I wonder if 1MB is just too low for FreeBSD. It looks like the stack sizing logic was directly ported from Linux. So maybe the solution would be to bump up the defaults. Does anybody have any clue as to why we would need a bigger native stack on Freebsd vs Linux? -- You are receiving this mail because: You are the assignee for the bug.help
