https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295900 Bug ID: 295900 Summary: panic: vn_irflag_unset_locked: some of the passed flags not set (have 0, passed 512) Product: Base System Version: 16.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: asomers@FreeBSD.org I've seen this panic twice today on 16.0-CURRENT. I can trigger it semi-reliably by running a sequence of basex commands.

() Steps to Reproduce ================== I don't have good steps to reproduce, unfortunately. I'm trying to get https://github.com/Vincent-Carrier/oxytone/ working, but the code on Github is incomplete, and I don't even have a working instance to compare with. So I'm kind of stabbing in the dark. But the command that triggered both panics was "just seed", which runs a bunch of basex commands. I'm using basex version 11.9 . -- You are receiving this mail because: You are the assignee for the bug.home | help
